PPSU belongs to the polysulfone series of materials. In addition, the Hurricane series also includes PSU and PES

PPSU is an amorphous and non crystalline materia， a high-performance plastic commonly used in food and medical devices. It is transparent and light yellow in color.
PPSU is a very safe material. It does not contain BPA. In the long-term use process, it will not produce other substances harmful to the human body. It has excellent temperature resistance and is suitable for food contact.
Moreover, PPSU material is a very durable material. It can withstand repeated disinfection without performance degradation. Therefore, PPSU is suitable for the manufacture of medical devices.

Thermal performance: Long term use temperature of 180 ° C, short-term use temperature of 200 ° C.

Impact performance: PPSU has excellent impact resistance, with impact strength superior to PSU and PES
NO BPA
High temperature steam hydrolysis resistance: can withstand multiple high-temperature steam disinfections without any performance degradation
Creep resistance
UV resistance
corrosion preventive
Has good biocompatibility
Flame retardant: UL94-v0
Insulation: Volume resistivity up to 1 * 1013
Easy to color

PPSU has various processing methods and low processing difficulty. It can be used for injection molding and foundation.
PPSU materials are often produced in the form of resins, because PPSU resins themselves have high impact resistance. The addition of glass fiber and carbon fiber reduces the impact resistance of PPSU.
Therefore, the PPSU produced by PRES only has different viscosity, fluidity and toughness. There is no fiber-modified PPSU material. If you need other PPSU materials, you can check out our agent's PPSU materials.

High flow PPSU

PPSU material has excellent toughness and impact strength superior to most engineering plastics. The extruded PEEK board and rod have excellent mechanical strength, high temperature steam hydrolysis resistance, and UV resistance, which allows them to withstand repeated disinfection.
After machining, it can be used as a component for food, drinking water contact, and medical equipment, with stable performance.
The transparent yellow appearance also makes the products of PPSU plate and bar have a certain aesthetic quality, and PPSU is an anti-aging material, which will not yellowing after long-term use.

PPSU has good fluidity and can quickly fill the mold during processing, improving production efficiency. This feature is beneficial for manufacturing components with complex shapes and precise dimensions.
The wide range of forming temperatures and thermal stability of PPSU are its processing characteristics: at high temperatures, PPSU materials exhibit good thermal stability, are not easily decomposed or discolored, ensuring the stability of the processing process and the reliability of product quality.
We have professional colorimeters that can meet customers' requirements for customized colors.
PRESS is able to design and manufacture PPSU molds based on drawings, select suitable materials for injection molding, and then export them globally.

PPSU injection molding

PPSU is also used in machining. The rigidity and strength of PPSU material enable PPSU to maintain dimensional stability and strong thermal stability during processing. It will not deform due to temperature rise during processing. The amorphous nature of PPSU reduces internal stress during cooling after processing, maintaining good impact resistance.
