Cte of polymer
WebPolyphenylene sulfide (PPS) is a semi crystalline, high temperature engineering thermoplastic. It is rigid and opaque polymer with a high melting point (280°C). It consists of para-phenylene units alternating with sulfide linkages. PPS offers an excellent balance of properties like: And, it can be easily processed as well as its toughness ... WebOct 1, 2024 · In practical applications, where a polymer matrix with lower intrinsic CTE is used, the CTE of the composite obtained by using this method of preparation can be reduced to an even lower level. This low CTE value will sufficiently close the gap between the CTE of the polymer matrix substrate materials and the wafer.
