Performance Description
Physicochemical properties
1. Polycarbonate, PC for short, It is the general name of a class of polymer compounds containing the structure of carbonate in the molecular chain and a variety of materials prepared with it as the matrix.
2. PC is a kind of amorphous engineering material, has a particularly good impact strength, thermal stability, gloss,
antibacterial characteristics, flame retardant characteristics, pollution resistance. The gap impact strength of PC is very
high, and the shrinkage rate is very low, generally 0.1%-0.2%. PC has good mechanical properties, but poor flow characteristics, so the injection process of this material is more difficult.
3. Pure polycarbonate resin is a kind of amorphous, tasteless, odorless, non-toxic, transparent thermoplastic polymer, molecular weight is generally 20,000-70000 range, relative density 1.18-1.20, glass transition temperature 140-150ºC, melting range 220-230ºC.
4. PC has certain chemical corrosion resistance and excellent oil resistance.
5. Polycarbonate is easy to absorb water, and the water in the high temperature process of molding processing will hydrolysis and degradation of polycarbonate, which seriously affects the appearance quality and physical and mechanical properties of products, so the control of water content is one of the keys to ensure the quality of products.
6. When choosing what kind of quality PC material, we should take the final expectation of the product as the benchmark. If the plastic parts require a higher impact resistance, then use low flow rate of PC material; Conversely, PC materials with high flow rate can be used, which can optimize the injection process.
