Unveiling the Material of Firefighter Helmet Visors: The Exceptional Performance and Applications of PPSU and PSU

PPSU Plastic Granules: The Perfect Blend of Toughness and Chemical Resistance

PPSU (Polyphenylsulfone) is a medium-viscosity, unreinforced injection molding and extrusion-grade plastic renowned for its exceptional toughness and chemical resistance. Below are four specific PPSU specifications:

P 3010 MR BLACK 10101

P 3010 MR GREY 30373

P 3010 MR WHITE 20264

P 3010

These PPSU plastic granules are optimized for demolding and are suitable for various injection molding and extrusion processes. They are widely used in fields that demand high toughness and chemical resistance.

PSU Plastic: Synonymous with High Rigidity and Strength

PSU (Polysulfone) is a high-performance engineering plastic known for its high rigidity and strength, making it suitable for a variety of demanding environments. Below are several PSU grades and their applications:

S 2010 G4 BLACK 15038: 20% glass fiber reinforced, medium-viscosity injection molding grade, suitable for circuit breaker components, lamp holders, heat shields, impellers, and printer cartridges.

S 2010 G4, S 2010 G6: Medium-viscosity injection molding grades with 20% glass fiber reinforcement, offering high stiffness and strength.

S 2010, S 3010 MR: Unreinforced, medium-viscosity standard injection molding grades.

S 3010, S 6010: Unreinforced, higher-viscosity injection molding and extrusion grades, providing greater toughness and better chemical resistance.
