PEEK & PEI & PPSU & PPS material

PRES provide high performance plastic material which:
Highly Electrical insulation:It can still maintain its insulation performance even in a high-temperature + high-voltage humid + corrosive environment.
High mechanical strength plastic material:Heat resistance & high strength
Excellent wear resistance:Heat resistance & wear resistance & high strength
ESD safe and conductive plastic material
Excellent toughness plastic material
PEEK material
PEEK material is currently one of thethe most outstanding comprehensive performance among thermoplastics. It has excellent high-temperature resistance, mechanical strength and fatigue resistance (currently, the fatigue resistance of PEEK material is at the top level).
Its melting point is extremely high at 343°C, and it can operate continuously at a temperature of 260°C.
Its corrosion resistance is also extremely excellent. Apart from concentrated sulfuric acid, it has very good resistance to other chemical substances.
PEI material
Polyetherimide (PEI, Polyetherimide) is a non-crystalline high-performance special engineering plastic, presenting a naturally amber color transparency. Its glass transition temperature can reach up to 217℃, and it can withstand long-term temperatures of 170℃ (short-term 200–230℃). 
It can keep high strength and Anti-rustility  at high temperatures,much better than PC, PA, PBT, etc., while cost much lower than PEEK, making it the most cost-effective option.
 
 
PPSU Material
Polyphenylsulfone (PPSU, Polyphenylsulfone) is a non-crystalline high-performance engineering plastic,with ultra-high toughness​,naturally amber transparency with light transmittance up to 88%. Its Tg 220℃, HDT 207℃, and it can withstand long-term service temperatures of 180℃ (short-term up to 207℃).
PPSU is completely BPA-free and outstanding hydrolytic stability and repeated-sterilization capability: PPSU survives 1,000+ cycles of 134℃ high-pressure steam autoclaving,reliable resistance to acids, alkalis, alcohols, oils, hot water and steam, it is the benchmark material for reusable medical devices
PPS plate and rods
Polyphenylene Sulfide (PPS) is a semi-crystalline high-performance engineering plastic, with exceptional heat resistance, inherent flame retardancy and outstanding chemical resistance. Its melting point reaches 280℃, continuous service temperatures of 200–240℃ (short-term up to 260℃).
PPS  flame retardant achieving UL94 V-0 at 0.38 mm, and offers excellent chemical resistance and extremely low water absorption (0.02%), excellent dimensional stability and outstanding electrical insulation.
 it is the benchmark material for under-the-hood automotive components, new energy vehicle high-voltage parts, high-temperature connectors and chemical pump & valve components.
As a high-performance plastic supplier in China, PRES offers a range of high-performanceplastic products, including plastic pellets, plastic plates, plastic rods, plastic tubes, plastic powders, and high-performance 3D printing filaments.
Meanwhile, we provide mold design & manufacturing & injection molding services.
