PBT Enhanced Filling Modifier

PBT is a milky white, semi-crystalline, translucent to opaque thermoplastic polyester. It is durable, fatigue resistant, self-lubricating, low friction coefficient, high heat resistance, and can operate under 140°C for extended periods of time.

It is flammable, decomposes at high temperatures, can withstand organic solvents but is not resistant to strong acids and alkalis.

It is widely utilized in the industries of automobiles, mechanical equipment, precise instrument components, electrical appliances, textiles, etc. because of its superior qualities.
The majority of PBT resins are created as blends, which can be altered with different additives and combined with other resins to provide materials with good overall heat resistance, flame retardancy, electrical insulation, and processing performance.

W5B is a graft polymer containing glycidyl ester functional group, polyolefin elastomer as matrix material, high reactivity and low residue.

One of the advantages of W5B is its low residue, which means that it can be used in applications where low levels of residual monomers or other impurities are desired. Additionally, the glycidyl ester functional group provides W5B with reactive sites that can be used for various functionalization reactions, such as cross-linking or modification with other chemicals.

Our synthetic resin’s many benefits include improved filling capabilities, superior mechanical qualities, outstanding thermal stability, and improved flame retardancy. It was created as a modifier for PBT enhanced filling. This synthetic glue finds use in the automotive, electrical and electronics, industrial equipment, and consumer products industries thanks to its compatibility, low viscosity, and chemical resistance. Our synthetic resin opens the door to creating high-performance, dependable, and secure products when added to PBT compositions.

Application case 1
Performance comparison of W5B and imported polyester tougheners in PBT toughening

Note: PBT Changchun, Taiwan 110 0 -211 M

It can be seen from the above table that the super toughening effect achieved by adding 15% W5B in the PBT toughening system is close to that of imported polyester toughening agents.

Application case2

Typical data of W5B in PBT fiber

Note: PBT Taiwan Changchun 110 0 -211 M GF Boulder 98 8 A

It can be seen from the above table that adding 5% W5B can improve the notched impact strength and preserve other properties in the PBT fiber-added system. It shows that W5B has superior processing performance in the PBT fiber-added system and can help the glass fiber to disperse uniformly.

Application case3
Typical Data of W5B in PBT Flame Retardant Reinforcement

Note: PBT Taiwan Changchun 110 0 -211 M GF Jushi 98 8 A Antimony trioxide Brominated epoxy

It can be seen from the above table that adding 4% W5B in the PBT flame retardant reinforcement system can improve the notched impact strength and preserve other properties well. It shows that W5B has superior processing performance in PBT flame retardant reinforcement system and can help glass fiber and flame retardant to disperse uniformly.

Product Advantage

1. strong strength, fatigue resistance, dimensional stability, and low creep (high temperature conditions rarely change);

2. heat aging: improved UL temperature index of 120 to 140 °C (excellent results for long-term aging outdoors);

3. resistance to solvents: no stress cracking; water stability: PBT is difficult to degrade in water;

4. electrical output:
— Excellent insulation (maintains electrical stability in humid, high-temperature conditions, making it the perfect material for the production of electronic and electrical parts);
–arc resistance: 120s; dielectric coefficient: 3.0-3.2

5. Molding processability: Extrusion or injection molding using standard equipment.

As well as having outstanding fluidity, the mold temperature is also lower than other specifications for engineering plastics. typically a few seconds, and typically 40 to 60 seconds for large components, can be spent on the processing of thin-walled parts.
