Recycling カジノ シークレット SUMIKASUPER LCP

Recycling カジノ シークレット LCP

When molded under appropriate molding conditions, SUMIKASUPER LCP exhibits excellent thermal stability and has excellent retention カジノ シークレット physical properties even when recycled and reused repeatedly. Since SUMIKASUPER LCP's strength and other properties are expressed through orientation, its electrical properties, flammability, chemical resistance, etc. do not change significantly when recycled and reused.
We evaluated the retention カジノ シークレット physical properties by changing the recycle ratio for a representative grade カジノ シークレット SUMIKASUPER LCP. At 30% recycling, a slight decrease in strength was observed in the early stages, but there was almost no change after the third recycling. At this time, the strength retention rate was over 90%, and almost no change in shrinkage rate was observed.

Property retention rate カジノ シークレット representative grades when regenerated

The physical property retention rate カジノ シークレット the representative grade recycled material is shown below when the recycled ratio is changed and the material is repeatedly molded. When using recycled materials, be sure to strictly manage the recycled material and determine the recycled material ratio after fully considering the needs and required quality カジノ シークレット the product.

Property retention rate カジノ シークレット representative grade (SV6808THF) when changing the recycled material ratio

According to UL regulations, SV6808THF can be regrind up to 70%. Table 4-4-2 shows the property retention rate when the recycled material ratio カジノ シークレット SV6808THF is changed. The allowable recycled material ratio varies depending on the product design level, UL standards, automotive standards, etc. Understanding the characteristics カジノ シークレット recycled materials and deciding on the recycled material ratio before using them will lead to lower costs and reduced environmental impact.
