heat-resisting gf30 PBT granules

The typical performance combination of high heat resistant PBT Valox resin includes excellent electrical strength, exceptional heat resistance, excellent corrosion resistance to various common chemicals, and good shielding performance. These PBT materials can be modified to provide excellent performance and meet various demanding applications. Has processing flexibility, higher quality, and productivity. All levels have been specially designed to achieve a first-class balance in physical, electrical, chemical, and aesthetic aspects to meet various applications. The processing characteristics include high fluidity, short production cycle, and excellent blow molding performance. In terms of aesthetics, it provides high glossiness and various visual effects. PBT raw materials include various standard and flame retardant grades, unfilled grades, and fiberglass filled grades of resins. Valox 420SEO resin is a global representative product of PBT, used in applications such as connectors and sensors under car engine covers, as well as components in high temperature and humidity environments. SABOC is a leading player in the field of PBT material alloy technology. With this professional advantage, Valox's material product line has a unique strong combination of chemical corrosion resistance and high impact resistance. The excellent impact resistance sets Valox raw materials apart, resulting in higher application value. Hydrolysis resistant and stable resins have stronger physical property retention ability. They exhibit excellent performance in high temperature/humidity environments.

The high heat resistant PBT Valox resin product series has a level suitable for the electrical industry, and they meet high RTI and GWIT application standards. They provide thermal stability and color stability, possess epoxy adhesive properties, can be laser etched on custom colors, and have flame retardancy. Compared with PA, it has stronger hydrolysis stability, meets higher CTI/GWIT electrical performance standards, can be used for thin-walled design, has dimensional stability, PBT raw material aesthetic level to improve product value, while ensuring product functional requirements. These grades of resin give your product a more aesthetically pleasing appearance, making it unique in the market. Reducing system costs in PBT production (eliminating secondary processing such as spraying), suitable for high-density PBT materials with high specific gravity Valox * resin with aesthetic application requirements, combining the inherent characteristics of PBT and the advantages of high mineral filling reinforcement materials. This raw material is resistant to chemical corrosion (various household cleaners and urea), aesthetically pleasing (color, metal, and granite like visual effects), and has the ability to repair (surface can be gently polished with sandpaper). High density Valox resin is the best material in the following fields, such as bathroom equipment and appliances (bathtubs, sinks, urinals, soap boxes, toothbrush bodies, toilet seats, etc.), Beautiful appearance of electrical/electronic equipment casings (speakers, remote controls, stereo equipment knobs/switches, kitchen equipment casings and handles), fashion industry (buttons, beads on fashion jewelry, etc.).
