ASA uPVC Sheet
ASA(Acrylonitrile styrene acrylate) uPVC(Unplasticized Polyvinyl chloride) Sheet

ASA uPVC Sheet

1. Surface Layer - Surface Layer- The Material is ASA(Acrylonitrile styrene acrylate) and ultra weather resin, to block the solar ultra violet and reduce the coefficient of heat conductivity, ensure product durability and resistance to chemical corrosion.

2. Underlying layer - contains Multi foam giving to the material light weight and improved sound and themal insulating properties and its a good material toughness special to ensure the strength at the same time, increase the rigidity and light illumination.

ASA is made by intoducing a grafted acrylic ester elastomer during a copolymerization of styrene and acrylonitrile (SAN). The finely divided powder is uniformly distributed in and grafted to the SAN molecular Chains. The outstanding weather ability of ASA is due to the acrylic ester elastomer.


DION ASA uPVC Sheet is an optimum choice for roofing & cladding in civil and industrial constructions as per the effeciency and benefits it provides. It can be used in many applications both exterior and interior. i.e. industrial Places, Commercial Places, Residential Places & Agricultural firms etc. like Factory Building, Warehouses, Market, Vehicle Parking sheds, Farm House, Water Resorts, Cottages, Chemical Industries, Animal House, Construction House, Schools, Colleges, Hotels, Sheltered Walkways, Security Guard Shelters, Roof Extensions, Summer Huts Cycles etc.

ASA parts have high gloss, good chemical and heat resistance, and high impact strength, even at low temperatures. Typical heat-deflection temperatures for ASA are 180 to 220 °F( 82 to 104 °C) at 264 psi. Tensile strengths are 4,000 to 7,000 psi; elongation at break, 25 to 40%, flexural modulus, 220,000 to 250,000 psi; and notched Izod impact strengths are 9.0 to 11.0 ft-lb/in. (at 73 °F) and 4.0 to 6.0 ft-lb/in. (at -40 °F).


  • Good Insulation - It is nonconductive and remains intact in case of accident discharge.
  • Fast Insulation - It is light and easy to be assembled and disassemblied, which enables fast installation.
  • Green and Environmental Friendly - Without any asbestos or radioactive element, it can be recycled and completely meets the requirement of environment protection.
  • Perfect Self - cleaning performance - The Surface is compact and smooth so it will not absorb dust. it is clean and looks new again after being washed by rain, then, no mark is left on the surface.
  • Stable Volume - The expansion coefficient is 4.93 x 10-5 mm/mm/0C, besides it also has a two way stretch perfomance on geometrical shape, which enagle it to accomodate to its extension even in case of big temperature change.
  • Excellent waterproof performance - The high weathering resistance resin adopted in the roofing tile is compact and does not absorb water. And the product is 45% wider than conventional ones; therefore it needs fewer joints and thus performs better waterproof function.
  • Good sound insulation - A test shows that this tile has good noise absorbing effect under noise of rainstorm and strong wind.
  • Excellent corrosion resistance - The experiment proves that this tile has no chemical reaction when it is soaked in salt, alkali and various acids under 60% for 24 hours. Our product is very suitable for coastal areas and places where acid rain often falls.
  • Strong fire resistance - According to GB8624-2006 standard detection conducted by the state autoritative department of fire prevention, its fire proofing perfomance is ≥ Class B.
  • Good resistance to impact - A test shows that the tile doesn't crack after 1 KG steel ball falls on it form 3 meters high. Moreover, the resistance to impact under low temperature is also very outstanding.
  • Excellent load carrying ability- The test shows that the roofing neither cracks not be damaged when the supporting spacing is 610mm and 150kg of load is applied. (2.0mm)
  • Color Lasting (One year warranty) - DION ASA uPVC Sheets consists ASA Material, which has extra lasting performance in the natural environment, even it exposed in the conditionals of Ultra violet Ray, Moisture, high and low temperature for a long term, it still can maintain the stability of the color.
  • Excellent Waterproof performance - The high weathering resistance resin adopted in the roofing sheet is compact and does not absorb water.
