When choosing door and window sealing strips in cold areas, it is important to consider the material’s low temperature resistance, elasticity retention ability and anti-aging performance.
Excellent cold resistance, it can maintain elasticity in the range of -40℃ to +120℃, and is not easy to harden or crack at low temperatures.
Also weather-resistant, resistant to UV rays, ozone and oxidation, suitable for areas with large temperature differences,
And has high softness, good sealing, and a long service life (more than 10 years).
It can effectively block cold air and reduce indoor heat loss.
It is especially suitable for doors and windows that are frequently opened and closed.
With excellent low temperature resistance, the operating temperature range in -60℃ to +200℃.
It performs stably in extremely cold environments.
It is non-toxic and environmentally friendly, suitable for places with high safety requirements (such as homes and hospitals).
The disadvantage is that the price is higher and the wear resistance is slightly inferior to EPDM.
It can be used in extremely cold areas with high environmental protection requirements.
Thermoplastic elastomers (TPE/TPV) material:
Have good elasticity and flexibility,
Low temperature resistance is close to EPDM (-30℃ to +80℃).
They are recyclable, environmentally friendly and easy to process.
The disadvantage is that they may gradually become brittle in severe cold.
Some customers will choose PVC material because it is cheap, but it has poor cold resistance, easy to harden and shrink at low temperatures, resulting in sealing failure. It is also easy to age, and its long-term outdoor service life is short (2-5 years). Therefore, avoid using PVC sealing strips in cold areas in winter.
