The English name of PEI Chinese polyetherimide board is Polyetherimide, PEI belongs to amorphous plastics. It is an amorphous high-performance polymer, which is extruded from engineering plastics made of amorphous PEI (polyetherimide) at high temperature by an extruder. At present, the commonly used PEI board is the raw material (Ultem) of GE in the United States. In 1972, GE of the United States began to research and develop PEI.
The Duratron® trademark includes 4 major categories of materials, each of which is subdivided into modified grades. Each modified material has different characteristics and applications. If necessary, please consult the professional sales team of Chengtu Plastics for detailed answers;
PMMA plexiglass material is characterized by low melting point, easy shrinkage, brittleness, and intolerant of organic solvents. PMMA material is used in the valve body, which has high transparency, easy observation, and high cost performance. It is a very commonly used material.
PEI machined parts are more cost-effective, only 1/3 of PEEK in terms of material, which can effectively reduce costs. The tooling and fixtures machined by PEI are mainly used in the 3C industry, such as mobile phone fixtures, inspection tools, tooling, etc.
PPS valve is an ideal alternative to PEEK as valve structural material. The cost is about 1/2 of that of PEEK. PPS has excellent corrosion resistance, high mechanical properties, and high dimensional stability. The best material for medium and high-end working conditions, with very good machinability.
Vespel sp1 is DuPont's pure grade PI profile product, which has excellent comprehensive mechanical properties, high temperature resistance and wear resistance, and is often used in extremely complex working conditions, such as aerospace, semiconductor, etc.
