(ABS), but with a much better UV-resistance, it is possible to use a high-quality ASA plastic, which is made of high-quality ASA plastic - with insect protection, white - produced according to DIN 1.4301 - properties of ASA (acrylonitrile / styrene / acrylic) and weather resistance. In the case of ASA, the acrylester is uniformly distributed in a SAN (styrene-acrylonitrile) polymer and is linked by grafted SAN chains. ASA forms high-quality, matt glossy and scratch resistant surfaces. ASA resist yellowing unlike ABS. ASA is resistant to aqueous chemicals. The very good chemical resistance is due to the higher polarity of the acrylic ester component compared to the polybutadiene component in ABS. ASA shows very good resistance against aqueous media including dilute acids / alkalis as well as wash liquors and a good resistance to oils / fats, alcohols and aliphatic hydrocarbons. ASA can also be used as a weather-resistant panel in building construction (PermaSkinTM), for high-heat consumed electrical equipment, for example, coffee machines and microwaves in the sports and recreation area as surfboard or also in the outer skin of cars. Can be used both indoors and outdoors. Ideal for ventilating closed residential and business premises, such as bathrooms, kitchens, toilets, offices, garages, damp rooms, exhaust systems or heating rooms. For back ventilation of cabinets with electrical installation. For ventilation of campers, boats and other vehicles. The grating has fixed horizontal blades which are easy to clean. The built-in net stops insects from getting in. - - Internal dimensions: 151 mm - outside dimensions / cover size: 179 mm.
