Flame-retardant thermal silica bulb thermal silica purchase thermal silica Which is better? This product can be combined at room temperature and moisture in the air to cause crosslinking, curing become high-performance elastomer is an excellent metallic and non-metallic materials, adhesives and thermal plastic; both bonding effect, and good thermal (heat) of; curing materials no obvious shrinkage and temperature; rubber nontoxic, noncorrosive, high temperature; perfectly good elasticity and toughness after curing colloid, fatigue, can take advantage of a silicone material excellent electrical characteristics within the range of -60 ~ 250 ° C to maintain elasticity. The series is a one-component, semi-flowing RTV silicone rubber, capable of a variety of electronic components for the sealing and the surrounding environment does not produce pollution, in full compliance with the EU RoHS directive. Features: ◆ strip smooth and delicate, extrusion rate is superior to metals and most plastics ◆ good adhesion ◆ non-corrosive, super anti-yellowing ◆ excellent electrical properties, good fight wear ◆ Excellent thermal performance, excellent The flame retardant (UL94 V0) Typical Applications: ◆ lighting fixtures, high-end fixtures ◆ ◆ The car lampshade adhesive sealing appliances panel, housing ◆ solar PV module frame, junction box and back sheet adhesive sealing ◆ various instruments of sealing technology parameters surgery: No. Test items found 1 2 Appearance White paste Density (g / cm3) 2.40 ± 0.20 3 dry time (min, 25 ℃) ≤20 4 Temperature (℃) -60 ~ 250 5 hardness (Shore A) 45-55 6 Tensile strength (MPa) ≥2.5 7 Elongation (%) ≥100 8 permittivity (1.2MHZ) 2.6-2.8 9 Dielectric Strength (KV / mm) ≥20 10 Volume resistivity rate (Ω · cm) 1.0 × 1015 11 Thermal conductivity [W / (m · K)] 1.4 ± 0.2 12 flammability rating (UL94) V0 (NOTE: Dry time (ASTM American Standard) means: at 25 ℃, 80% relative humidity, specific time sizing, the glass rod with a smooth round light contact surface sizing, surface sizing glass rod round leaving no adhesive residue left behind, known as surface dry.)
