What is LASULF G/20

LASULF G/20 is a glass fiber reinforced polysulfone plastic filled with 20% glass fiber, and its flame retardant grade can reach V-0. Compared with ordinary polysulfone, it maintains excellent heat resistance and electrical insulation performance while significantly enhancing mechanical strength and dimensional stability, making it highly suitable for applications with high temperatures, high loads, and strict safety requirements.

01 | Core Features

High strength and flame retardancy: The glass fiber filling enhances the material's rigidity and impact resistance, while meeting both V-1 and V-0 flame retardant standards.

Heat resistance and dimensional stability: The heat distortion temperature can reach 185℃, and the long-term service temperature can reach 160℃. The products are not prone to warping or deformation.

Reliable electrical performance: The insulation strength can reach 19 KV/mm, with excellent surface resistance and volume resistance, making it suitable for electronic and electrical applications.

Low smoke and low toxicity: The smoke and toxicity produced during the flame retardant process are relatively low, which better meets safety and environmental protection requirements.

Chemical resistance: It can resist common acids, alkalis and some organic media, ensuring long-term stability.

Disinfection resistance: It can withstand high-pressure sterilization and repeated thermal disinfection, making it suitable for medical and laboratory use.

02 | Typical Applications

Electrical and electronic components: switches, coil bobbings and electronic parts, which need to take into account both flame retardancy and insulation performance.

Automotive electronics: Precision components used in high-temperature environments such as sensor housings and electronic control parts.

Industrial equipment: Valves, pump bodies, pipeline fittings, stable for a long time in chemical and high-temperature environments.

Household appliances: microwave oven accessories, heater casings and other high-temperature working parts.

Medical and laboratory equipment: Medical device parts that can be repeatedly sterilized by steam or heat.

04 | Advantages in Processing and Design

Processing method: Injection molding performs well and can be used to produce components with complex structures.

High structural accuracy: Glass fiber reinforcement reduces warpage and deformation, making it suitable for precision parts.

Flame retardant and controllable: V-1 or V-0 can be achieved at different thicknesses, flexibly meeting various safety requirements.

05 | Industry Trends

Replace traditional materials: Lighter and easier to process than metals and thermosetting plastics.

Regulatory compliance drive: The demand for high-performance flame-retardant materials is on the rise in electronic, automotive and industrial applications.

Sustainable development: High-temperature resistance and chemical resistance extend the service life of products and reduce the frequency of maintenance and replacement.
