  2. Acrylonitrile butadiene styrene - Wikipedia

    en.wikipedia.org/wiki/Acrylonitrile_butadiene...

    Acrylonitrile butadiene styrene (ABS) (chemical formula (C 8 H 8) x · (C 4 H 6) y · (C 3 H 3 N) z) is a common thermoplastic polymer. Its glass transition temperature is approximately 105 °C (221 °F). [4] ABS is amorphous and therefore has no true melting point. ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the ...

  3. Styrene-acrylonitrile resin - Wikipedia

    en.wikipedia.org/wiki/Styrene-acrylonitrile_resin

    Like polystyrene itself, it is transparent and brittle. The copolymer has a glass transition temperature greater than 100 °C owing to the acrylonitrile units in the chain, thus making the material resistant to boiling water. It is structurally related to ABS plastic, where polybutadiene is copolymerised with SAN to give a much tougher material ...

  4. Twinwall plastic - Wikipedia

    en.wikipedia.org/wiki/Twinwall_plastic

    Although single layer polycarbonate sheeting is more flexible than polycarbonate in twinwall configuration, it still retains significant advantages over alternative materials, including glass. A typical 6mm sheet has a density of 0.72 g/cm^2 [ 6 ] and a thermal insulation R value of 0.3 m^2°C/W, while allowing 80% of visible light pass through ...

  5. Polycarbonate - Wikipedia

    en.wikipedia.org/wiki/Polycarbonate

    Thermally processed material is usually totally amorphous, [7] and as a result is highly transparent to visible light, with better light transmission than many kinds of glass. Polycarbonate has a glass transition temperature of about 147 °C (297 °F), [8] so it softens gradually above this point and flows above about 155 °C (311 °F). [9]

  6. Acrylonitrile styrene acrylate - Wikipedia

    en.wikipedia.org/wiki/Acrylonitrile_styrene_acrylate

    ASA has lower glass transition temperature than ABS, 100 °C vs 105 °C, providing better low-temperature properties to the material. [3] ASA has high outdoor weatherability; it retains gloss, color, and mechanical properties in outdoor exposure. It has good chemical and heat resistance, high gloss, good antistatic properties, and is tough and ...

  7. Royalex - Wikipedia

    en.wikipedia.org/wiki/Royalex

    Royalex was a composite material, comprising an outer layer of vinyl and hard acrylonitrile butadiene styrene plastic (ABS) and an inner layer of ABS foam. The layers are bonded by heat treatment. [1] It was used to manufacture durable, mid-priced canoes. Its supplier closed out production of the material in 2014.
