Fire doors and windows seal swell Product Description Fire and smoke seal swell rapidly expands when heated in a closed door, window gaps and prevent smoke and heat fleeing seal species, to ensure personal safety. 1) Ingredients: hydrated sodium silicate, glass, additives, epoxy coating 2) expansion temperature: the initial expansion temperature 199 ℃, the main expansion temperature 347 ℃; the temperature rose to 980 ℃ and maintain 30min, no burning, no ash technology; 3) heat and flame and its performance: doors installed seals left, right and upper side of the gap at no significant leakage of smoke, within a certain time (up to 120 minutes) to maintain good performance of the fire and the smoke. Low reaction temperature, short reaction time to begin to swell, linear expansion multiples larger than the original thickness of the expansion of three times; 120 ° C can produce significant bubble pressure, fire and smoke performance combined reach insulation and noise isolation, The fire protection board as a "fire expansion of construction materials" used in fireproof construction elements in Germany has been approved by the relevant regulatory and construction law. 4) resistance to environmental capacity: Place 120 days at room temperature, 90 humidity expansion ratio unchanged. 5) Regular Size: 2mm * 20mm * 1050mm, 2mm * 15mm * 1050mm, 2mm * 10mm * 1050 (can be used with customer specified size). Ethylene propylene diene monomer (EPDM) seals forming a microwave curing process, smooth surface appearance, has good flexibility and resistance to compression, a variety of weather-resistant seal, ozone resistance, chemical action and wide temperature range (-40 + 160), excellent performance, has been manufacturing a wide range of automotive applications, such as curtain walls and windows. Different shapes, different materials, or cold, heat, foam, solid body, as well as products with specific performance requirements, can meet the requirements for the design and use. Features: EPDM as raw material, the surface smooth and detailed, good elasticity, good foam evenly, waterproof performance of first-class, anti-ozone, anti-aging, solvent resistance are good. EPDM / rubber / foam products: a polyethylene foam rubber expansion joint plate openings (. Caulk board caulking board) (a) Product Features ▲ light weight, high strength stretching, does not absorb water (instead of the traditional The three oil four felt, asphalt cedar wood panels and other materials). Product environmental seal of good quality, simple construction, seepage, leakage, good sealing effect. ▲ corrosion resistance, aging resistance, high temperature + 80 ℃ ~ -45 ℃ not flowing, no distortion, no rattle, long service life. ▲ with independent air bubble structure, a special type of joint appearance of honeycomb plate holes evenly distributed, you can not fight hair and cement / adhesive sealant tightly integrated, adapt to the natural expansion and contraction of change, enhance joint sealing expansion of the sealing effect. (B) the application of the product can be widely used in machinery, doors, windows, walls, rivers, dams, ports, docks, underground cave Chung, water power, airports, bridges and other engineering concrete sealing seams. (C) the construction of the product according to the situation using a variety of methods can use the product to use. Longitudinal seam sealing, horizontal sealing joints and other special seam sealing strip manufacturer | seals | Rubber Products offered by Via Via Rubber Products Co. Qinghe County.
