ASA/PVC Hollow Tile

ASA synthetic resin tiles have dominated the market as a novel roofing material, playing a significant role in projects ranging from the Beijing Olympics to the urban redevelopment for the Shanghai World Expo, and from large-scale rural construction to the modernization of factory buildings. In the market recently, a new type of ASA/PVC hollow tile has quietly emerged, particularly gaining popularity in some high-humidity and hot climates in Southeast Asia. Below is a brief introduction to ASA/PVC hollow tiles.

The ASA/PVC hollow tile consists of an upper layer (ASA color co-extrusion material) and a lower layer (PVC with calcium powder filler). The cross-section features a continuous rectangular hollow structure with a high-profile wave design. The thickness is 14mm, width is 850mm, with the upper layer of the tile being 1.4mm, the lower layer 1mm, ribs 0.8mm, wave height 42, and weight 4.7kg/m2. The blue surface layer is co-extruded ASA with a thickness of 0.15mm.

Looking at the design structure of ASA/PVC hollow tiles, compared to ASA synthetic resin tiles, this product has the following characteristics:

  • Excellent heat insulation and thermal retention (lower thermal transmission coefficient than 3mm ASA synthetic resin).
  • Lighter weight per unit (approximately 20% lighter than 3mm ASA synthetic resin tiles).
  • Lower cost (15-20% lower than 3mm ASA synthetic resin tiles, with a formula similar to ASA synthetic resin tiles).
  • Better sound insulation (due to the 14mm hollow structure).
  • Equivalent weather resistance.
  • Comparable initial load resistance.

The production equipment for ASA/PVC hollow tiles is the same as that for ASA synthetic resin tiles, using a plastic tile molding machine. However, the extrusion mold is different and includes a vacuum forming section. The structure is simple, and operation is easy. Since the mold and forming sections differ from ASA synthetic resin tiles, with less adjustability, there is a higher demand for the flow properties of ASA color co-extrusion material. Common ASA materials may experience defects such as flow marks, whitening, streaking, and unevenness.

Classification of Engineering Plastics

By Purpose

  • General Plastics:Commonly referred to as general plastics, these are large in production, low in cost, versatile, and widely used. Examples include polyethylene, polypropylene, polyvinyl chloride, polystyrene, ABS (acrylonitrile-butadiene-styrene), polymethyl methacrylate, and amino plastics. They constitute over 90% of the total plastic production, earning them the name “bulk plastics.”
  • Engineering Plastics: These plastics serve as engineering materials and can replace metal in manufacturing machine components. Engineering plastics exhibit excellent comprehensive performance, high rigidity, low creep, high mechanical strength, good heat resistance, good electrical insulation, and can be used long-term in demanding chemical and physical environments. They can substitute for metals as structural materials in engineering. However, they are more expensive and have a smaller production volume. Engineering plastics can be further divided into general engineering plastics and special engineering plastics. Examples of general engineering plastics include polyamide, polycarbonate, polyoxymethylene, modified polyphenylene ether, and thermoplastic polyester. Special engineering plastics include heat-resistant plastics with a temperature resistance above 150°C, such as polyimide, polysulfide, polyarylate, aromatic polyamide, polyarylester, polyphenylene ester, polyaryletherketone, liquid crystal polymers, and fluororesins.

By Thermal Forming Processing Performance

  • Thermosetting Plastics:These plastics soften and flow during the first heating, undergo a chemical reaction to crosslink and solidify at a certain temperature, and this change is irreversible. They cannot soften and flow again upon reheating. Examples include phenolic, urea-formaldehyde, melamine-formaldehyde, epoxy, unsaturated polyester, and organosilicon plastics. Thermosetting plastics form a three-dimensional network structure after resin curing, making them unable to melt or dissolve in solvents. They are commonly used in applications requiring heat insulation, wear resistance, insulation, and high-voltage electrical properties.
  • Thermoplastic Plastics:These plastics soften and flow when heated, solidify when cooled, and this process is reversible. Examples include polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyacetal, polyethylene terephthalate, and polyamides. Thermoplastic plastics have linear or branched molecular structures, and there are no chemical bonds formed between molecular chains during the molding process. They soften upon heating and solidify upon cooling, undergoing a physical change.

By Transparency

  • Transparent Plastics:Plastics with a light transmittance of over 88% are classified as transparent plastics. Examples include polymethyl methacrylate (PMMA), polystyrene (PS), polycarbonate (PC), and Z-polyester.
  • Translucent Plastics:Examples include polypropylene (PP), polyvinyl chloride (PVC), polyethylene (PE), acrylonitrile-styrene (AS), polyethylene terephthalate (PET), methyl methacrylate-butadiene-styrene (MBS), and polystyrene film (PSF).
  • Opaque Plastics:Mainly include polyoxymethylene (POM), polyamide (PA), ABS, high-impact polystyrene (HIPS), and polyphenylene oxide (PPO).

By Hardness

  • Hard Plastics:Examples include ABS, POM, PS, PMMA, PC, PET, PBT, and PPO.
  • Semi-Hard Plastics:Examples include PP, PE, PA, and PVC.
  • Soft Plastics:Examples include soft PVC, thermoplastic elastomers (TPE), thermoplastic rubber (TPR), ethylene-vinyl acetate (EVA), and thermoplastic polyurethane (TPU).

By Chemical Structure

  • Polyolefin Plastics:Examples include LDPE, MDPE, HDPE, LLDPE, UHMWPE, and PP.
  • Polystyrene Plastics:Examples include PS, AS, BS, ABS, MBS, and HIPS.
  • Polyamide Plastics:Examples include PA6, PA66, PA610, PA10T, and PA612.
  • Polyether Plastics:Examples include PEEK, POM, PPS, and PPO.
  • Polyester Plastics:Examples include PBT and PET.
  • Acrylic Plastics: Example is PMMA.

Advantages of ASA Weather-Resistant and UV-Resistant Properties

ASA, an acronym for Acrylonitrile Styrene Acrylate, is a graft copolymer of acrylic ester, acrylonitrile, and styrene. The outer layer consists of graft polystyrene-acrylonitrile copolymer, abbreviated as SAN, while the core of the copolymer is polybutyl acrylate rubber, abbreviated as PBA.

ASA possesses an exceptionally strong resistance to ultraviolet (UV) radiation, making it suitable for outdoor injection-molded products exposed to direct sunlight, ensuring resistance against UV fading and yellowing.

Four Key Advantages of ASA:

  • Mechanical and Physical Properties: ASA exhibits excellent mechanical and physical performance.
  • Weather Resistance: ASA demonstrates strong resistance to weathering.
  • High-Temperature Resistance: ASA performs well under high-temperature conditions.
  • Antistatic Properties: ASA acts as an antistatic material, reducing the accumulation of dust on the surface.

Polymeric materials with double bonds are susceptible to the opening of these bonds by the intense ultraviolet radiation from sunlight, leading to a decline in the aging resistance of the polymer.

ASA addresses this issue by substituting unsaturated double bonds in the butadiene rubber of ABS with acrylic acid rubber that lacks such bonds. This substitution not only resists degradation, aging, and fading caused by UV exposure but also provides robust protection against decomposition or discoloration resulting from high temperatures during oxidative processing in the atmosphere. Consequently, this significantly enhances the material’s resistance to aging and weathering.

According to test results, ASA exhibits aging resistance more than ten times that of ABS.

Application of ASA Material in PVC Resin Tiles

In the production process of synthetic resin tiles, a crucial step is co-extrusion. In this manufacturing process, the flow properties of ASA co-extrusion material, the compatibility with PVC base material, the amount of added water-cut material in PVC base material, the quality of the mold, temperature control, the technical proficiency of operators, and their sense of responsibility all have direct and indirect impacts on the uniformity, whitening, scratching, impact resistance, weather resistance, and other quality aspects of the PVC tile surface.

ExcelChemic’s ASA weather-resistant functional film, in comparison to co-extrusion and composite technologies, brings revolutionary changes. It effectively addresses the influences of the mentioned factors on product quality. Through modification technology, the composite of ASA film and PVC tiles prevents layering and cracking. It meets quality requirements in high and low-temperature resistance experiments without film layer separation.

Our ASA weather-resistant film exhibits higher toughness than commercially available co-extruded ASA materials, with superior tensile and impact strength. Consequently, under the same PVC tile strength, it significantly reduces the cost of PVC base materials. For every percentage point increase in the toughness of ASA weather-resistant film, the co-extrusion cost of PVC tiles can be reduced by 20-30 percentage points. Using high-toughness ASA weather-resistant film proves to be an effective means of cost savings.
