Mainstream aluminum alloy doors and Windows sealing rubber strip product performance PK.
Aluminium alloy doors and Windows seal tape performance is different, how to distinguish. Doors and Windows sealing strip is often used in building Windows and doors curtain wall components, such as glass and layering, glass and fan, box and fan etc. Combining site, its design is achieved by extrusion deformation, doors and Windows seal for air, liquid, dust, etc, in order to achieve the doors and Windows heat insulation, sound insulation, heat preservation, dustproof, waterproof, etc. So, the door and window seal tape should have good rebound, sealing, weatherproof, ability to have the effect of heat insulation, sound insulation, dustproof and waterproof.
Door window sealing strip although the proportion is small, but the action is not small. Inferior door and window seal strip not only not environmental protection, the peculiar smell that contains, can cause harm to your body, pollute air. At present, the commonly used in aluminum alloy doors and Windows sealing strip on the mainstream products are: PVC, EPDM (EPDM), thermoplastic elastomer (TPV), silicone rubber, etc., each have each advantages and disadvantages on performance.
1. PVC seal tape.
And cracks. Can be welded.
Proportion: high-grade 1.5g/cm3; 1.6 g/cm3 mid-range; Low of 1.7 g/cm3.
Service life: 1-3 years. Since PVC products contain halogen, the stabilizer contains heavy metals, so it is not environmentally friendly, so the developed countries and coastal cities in China have eliminated or restricted the use of PVC strips.
Recommendation index: not recommended.
Ii. EPDM (EPDM) seal tape.
Performance: good weather resistance, ozone resistance and anti-aging properties; Better comprehensive physical mechanical properties; It is also very good at photooxidation. No color adjustment, no welding.
Weight: 1.3 to 1.35 g/cm3
Service life: more than 20 years, product environmental protection, product construction is simple, anti-seepage, leakproof, water stop effect good.
Recommendation index: recommended for general engineering non-freezing area.
3. TPV (thermoplastic elastomer) sealing tape.
Performance: excellent anti-ozone and weather aging properties; Good comprehensive physical mechanical properties, also excellent in light oxidation. Adjustable color can be soldered.
Weight: 1.05 to 1.15 g/cm3
Service life: over 25 years.
Recommendation index: recommended for cold regions.
4. Silicone rubber seal tape.
Performance: excellent ozone resistance and weather resistance; Excellent elasticity and good compression deformation; Adjustable color, color fastness high. Do not weld.
Weight: 1.18 to 1.25 g/cm3
Service life: over 50 years.
Recommended index: cold region/high grade engineering recommended.
