One-Part Dispensable Gap Filler

TM series one-part dispensable gap fillers are a kind of silicone thermal conductive products with strong plasticity. The application process can be made into sheet products with high compression rate or semi-flow state to meet the automatic dispensing process according to the needs of customers. It has high efficiency of thermal conductivity and excellent caulk effect, and is mainly used in low pressure and the demand for silicon volatilize.
Features: 3.0 ~ 8.0 W/m.K, no cure required, highly compliant, low pressure vs deflection, liquid adhesive.
Applications: networking and telecommunications, notebooks, tablets, memory modules, industrial: LEDs, power supplies, power bank fast charger.
