Product Description

PC/Polycarbonate - Hubei Ganning 3010R B medium viscosity injection grade polycarbonate, with a blue base that is easy to demould and a medium viscosity universal polycarbonate. It has small molecular weight fluctuations, regular molecular structure, and short high-temperature thermal history, and can be widely used in fields such as automotive electronics, sheet and film, optics, etc. Polycarbonate (PC) is a polyester type of carbonate, and carbonate itself is not stable, But its derivatives (such as phosgene, urea, carbonates, carbonates) all have certain stability.
According to the different structures of alcohols, polycarbonates can be divided into two categories: aliphatic and aromatic.
Aliphatic polycarbonate. For example, polyethylene carbonate, trimethylene carbonate and their copolymers have low melting point and glass transition temperature, poor strength, and cannot be used as structural materials; However, utilizing its biocompatibility and biodegradability, it can be applied in areas such as sustained-release release carriers, surgical sutures, and bone support materials.
Polycarbonate is resistant to weak acids, weak alkalis, and neutral oils.
Polycarbonate is not resistant to ultraviolet light and strong alkalis.
PC is a type of linear carbonated polyester, with alternating carbonate groups and other groups in the molecule. These groups can be aromatic, aliphatic, or both. Bisphenol A type PC is the most important industrial product.
PC is an amorphous polymer with almost colorless glass state and excellent optical properties. PC high molecular weight resin has high toughness, with a notch impact strength of 600-900J/m for cantilever beams, and an unfilled grade with a thermal deformation temperature of approximately 130 ° C. Glass fiber reinforcement can increase this value by 10 ° C. The bending modulus of PC can reach over 2400MPa, and the resin can be processed into large rigid products. At temperatures below 100 ° C, the creep rate under load is very low. PC has poor hydrolysis resistance and cannot be used for products that repeatedly undergo high-pressure steam.
The main performance defects of PC are insufficient hydrolysis stability, sensitivity to notches, poor resistance to organic chemicals, and poor scratch resistance. Long term exposure to ultraviolet light can cause yellowing. Like other resins, PC is susceptible to erosion by certain organic solvents.
