Product Description

Polycarbonate (PC) is a polyester of carbonic acid. Carbonic acid itself is not stable, but its derivatives (such as phosgene, urea, carbonates, carbonates) have a certain degree of stability.

According to the different alcohol structures, polycarbonate can be divided into two categories: aliphatic and aromatic. Polycarbonate

Aliphatic polycarbonate. Polyethylene carbonate, polytrimethylene carbonate, and their copolymers have low melting points and glass transition temperatures, poor strength, and cannot be used as structural materials; However, by utilizing its biocompatibility and biodegradability, it can be applied in drug delivery carriers, surgical sutures, bone support materials, and other fields.

Polycarbonate is resistant to weak acids, weak bases, and neutral oils.

Polycarbonate is not resistant to ultraviolet light and strong alkali.

PC is a linear carbonate polyester with alternating arrangement of carbonate groups and other groups in the molecule, which can be aromatic, aliphatic, or both. Bisphenol A-type PC is the most important industrial product. AS Resin

PC is an almost colorless glassy amorphous polymer with excellent optical properties. PC high molecular weight resin has high toughness, with a cantilever beam notch impact strength of 600-900J/m. The unfilled grade has a thermal deformation temperature of approximately 130 ° C, and 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. Below 100 ° C, the creep rate under load is very low. PC has poor hydrolysis resistance and cannot be used for products that are repeatedly subjected to high-pressure steam. Polypropylene

The main performance defects of PC are insufficient hydrolysis stability, sensitivity to notches, poor resistance to organic chemicals, poor scratch resistance, and yellowing when exposed to ultraviolet light for a long time. Like other resins, PC is susceptible to erosion by certain organic solvents.

PC materials have flame retardancy. Antioxidant activity.
