Mold insulation board resin and application production, high temperature resistance is the topic that researchers are most concerned about, for example: polyphenylene sulfide is well known for its heat resistance. However, its inherent brittleness limits its use in applications requiring flexibility and toughness, such as metal pipes or airless piping systems. Novel elasticity with low temperature impact strength with heat resistance up to 200 degrees and above was evaluated. A comprehensive study presents the material's mechanical, thermal and corrosion resistance properties, as well as barrier permeation properties. Mold heat shields also require low temperature shock resistance to prevent damage. In order to create mold heat shields with good impact performance and aesthetics, it seems that the key is in the bond structure of the copolymer, specifically the distribution of PDMS fragments in the chain structure, which can form in-blocks in the material, resulting in Aesthetics issues. Temperature and impact resistance are also a point of interest when discussing mold insulation board polymers. Phosphorus-based flame retardants used in alloys and blends for impact-resistant PC blends whose impact properties may be destroyed by liquid phosphorus.
