How to optimize the use of plastic products in the selection of raw materials?

1, first of all, in the selection of raw materials for plastic products, the appearance of the material greatly affects people's impression of the product, appearance, including whether the plastic is transparent, whether good optical properties (for optical products), the original color of the plastic and can be stained, can be dyed bright colors, surface roughness of the plastic, the brightness of the plastic affects the scope of use of plastic parts.

2, followed by the mechanical properties of the material is the plastic parts, especially engineering plastic parts with the selection of key assessment indicators.

3, the last mechanical properties of the material are mainly the following aspects: strength: the strength of the material, usually tensile strength, compression strength, bending strength, etc., but commonly used tensile strength to assess the mechanical properties of the material, but also should pay attention to the material in the tensile stress - strain curve, from which you can get the yield strength of the material, strength at break, Modulus, elongation at break, the material is brittle or toughness damage when pulled off the information, the impact strength of the material, especially the notched impact strength is an important indicator of the toughness of the material.
