PC is almost colorless glassy amorphous polymer with good optical properties. PC high molecular weight resin has high toughness, cantilever notch impact strength of 600~900J/m, unfilled grade thermal deformation temperature of about 130°C, glass fiber reinforced can increase this value by 10°C. PC bending modulus can reach more than 2400MPa, 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 to repeatedly withstand high pressure steam products.

The cubic boron nitride has a molecular formula of BN. Its atomic structure is similar to the structure of carbon atoms in diamond. Therefore, it has high-density characteristics, hardness is slightly lower than that of diamond, and its hardness is second only to diamond but much higher than other materials. Therefore, it is commonly used as an abrasive and a tool material together with diamond as a superabrasives material.

Dyes are compounds that can impart bright and durable colors to other substances in a molecular or dispersed state. In the printing and dyeing process, besides using raw dye powder, dye auxiliaries are also added to enhance dyeing efficiency and effectiveness. Among these auxiliaries, dye dispersants play a vital role. Dye dispersants are non-ionic surfactants that aid in achieving a leveling effect, maintaining dye dispersion, preventing aggregation and precipitation, and improving dye solubility. By incorporating dispersants and protective colloids, uniform dyeing is ensured, and stains are prevented.
