How to solve the toughness and high-temperature resistance in industrial mold silicone?
Industrial mold silicone has long been widely used in the construction industry, such as European components, Roman columns, sculptures, cultural stones, gypsum lines, etc.! It is also mainly used for resin craft gift mold replication in regions like Zhejiang! Industrial-grade mold silicone, as the primary mold replication material, has advantages over other ordinary materials: it can completely replicate every part of fine products! Moreover, it has strong tensile strength and heat resistance, allowing for repeated use!


First, we need to understand that industrial-grade mold silicone is divided into two types: milky white and semi-transparent, composed of silicone and curing agent in a ratio of 100:2. Among them, the semi-transparent HF-308 model offers strong tear resistance and a long service life! So, what are the reasons for poor tensile strength and heat resistance during use?

First, before ordering, it is necessary to communicate with the supplier about the product operation method and suitable hardness to configure the corresponding silicone raw materials. The best hardness range is typically between 20 and 30 degrees, which provides strong toughness! During the operation of industrial mold silicone, fiber cloth is used to enhance tensile strength. After completion, it is best to let it rest for 12 hours before putting it into production!

Second, if the product requires higher heat resistance, it is essential to inform the supplier in time so that the engineers can prepare heat-resistant silicone raw materials according to requirements. For example, products that require high-temperature operations, such as resin, can be easily handled! However, for special products requiring even higher heat resistance, high-temperature food-grade mold silicone HF-7509 can be used for mold replication, with heat resistance reaching over 350 degrees!
