PPSU (Polyphenyl sulfone resin) is an amorphous thermoplastic super engineering plastic. It has strong impact toughness, chemical stability and hydrolysis resistance. The product can withstand repeated steam disinfection and can be used for a long time at l80°C.
PPSU as the most ideal material for food contact, the reason why it can stand out among many materials, instead of glass, metal and ceramics, used in household goods and daily necessities, because it has the following advantages:
PPSU has good toughness and chemical resistance, excellent hydrolysis stability and dimensional stability, with high strength and stiffness, while having a certain toughness, can withstand large pressure and impact load, suitable for pipeline system components.
PPSU | PPSU Specification |
P200 | High viscosity, toughness, better impact resistance |
P300 | Medium viscosity, good machining performance, good toughness, excellent impact resistance, and excellent chemical resistance |
P300Q | Medium viscosity, the same mechanical properties and processing properties, with better optical properties, lighter color, higher light transmittance. |
P320 | Medium viscosity, good machining performance, and better fluidity while maintaining the inherent viscosity |
PSOO | Low viscosity with good fluidity |
P300BK | Medium viscosity, color changing material for plumbing fittings |
P300WH | Medium viscosity, special material for changing the color of tableware |
