SUMIKASUPER LCP shows excellent カジノ シークレットrmal stability when molding is performed under proper molding conditions, and it is able to retain its physical properties even after repeated recycling.
For representative grades カジノ シークレット SUMIKASUPER LCP, changes in properties were evaluated when the use ratio カジノ シークレット recycled materials and their recycling number were varied. (see Figure 4-4-1 ,4-4-2 and Table 4-4-1) The use カジノ シークレット recycled materials slightly degrades the properties カジノ シークレット SUMIKASUPER LCP, but they are not degraded significantly even when the recycling number カジノ シークレット recycled materials is increased.
When using recycled materials, it is necessary to carefully manage the quality カジノ シークレット the recycled materials. In addition, the ratio カジノ シークレット recycled materials to be used and the limit on the recycling number should be determined based on the required characteristics and quality カジノ シークレット the molded products.
