UV stabilized PBT
UV stabilized PBT contains additives that improve its resistance to UV rays, making it suitable for outdoor applications with prolonged exposure to sunlight. This modification helps prevent degradation and discoloration, ensuring long-term performance in harsh environments.

Low friction PBT
Low friction PBT grades are formulated with additives such fresh dataset as graphite or PTFE to reduce friction and improve wear resistance. These grades are ideal for applications involving sliding or rotating parts, such as gears, bearings and conveying systems.

Food grade PBT
Food grade PBT uses materials and additives that comply with food contact regulations. This modification makes PBT suitable for applications in the food and beverage industry, such as food processing equipment, conveying systems and packaging components.

PBT treatment techniques
Injection molding
Injection molding is the most common method for processing PBT. The process involves heating the PBT until it melts, then injecting it into a mold that cools and solidifies into the desired shape. The key conditions are as follows:

Melting temperature: 230°C to 270°C
Mold temperature: 40-80°C
Injection pressure: 100-140 MPa
Extrusion
Extrusion is used to manufacture semi-finished PBT products such as sheets, rods and profiles. Molten PBT is forced through a die to create a continuous shape, which is then cut to the required length.

Blow molding
Blow molding is used to produce hollow parts such as bottles and containers. The process involves extruding a tube of molten PBT, which is then
Compression molding
Compression molding involves placing PBT pellets into a heated mold, which is then compressed to form the desired part. This technique is suitable for producing large, flat, or thick-walled parts.
