ABS (acrynonitrile-butadiene-styrene) Thermoplastic copolymer obtained by polymerization of acrylonitrile, styrene, butadiene. Back Pressure Pressure which is applied to the rear end of the screw and causes a slowing of its translation backwards while the molten material accumulates in the injection chamber due to the rotation of the screw itself. Cylinder Part of the injection group,… Continua a leggere Plastic materials vocabulary
The main physical properties of a thermoplastic and thermosetting products are: Extreme solidity at ambient temperature Excellent electrical isolation Excellent thermal and acoustic insulation Great portability and ease of use thanks to its light weight Durability Resistent to atmospheric agents Liquid and gas impermeability Thermoplastic products are very resistant to acids Thermosetting products are very… Continua a leggere The main physical properties of plastic
Back in 1909, the belgian-american chemist Leo Baekeland made a discovery that still nowdays gave him a reputation of being one of the most influential scientist in history: he discovered the bakelite, the first thermosetting plastic material! Studying two derivatives of petroleum – phenol and formaldehyde – Baekeland invented a material that even if heated… Continua a leggere Plastic Materials. The first synthetic plastic in history
