Sponge sealing strip profile, a sponge seal.Low density, excellent sealing, cushioning and elasticity.

Sponge sealing strip profile can be manufactured by mechanical foaming of latex, slow gelation and injection molding.Or made by continuous extrusion and vulcanization of foamed rubber.Used for vehicle door and window sealing.

Sponge sealing strip profile is a new material developed on the basis of introducing technology from abroad and independently developing at home in recent years, mainly used in transportation, construction and other fields.

Its outstanding advantages are:

(1) The performance and service life of Sponge sealing strip profile are equivalent to that of vulcanized EPDM rubber seals.

(2) The processing energy consumption of Sponge sealing strip profile is lower than that of vulcanized EPDM strip (equivalent to PVC).

(3) Sponge sealing strip profile does not contain heavy metals such as halogen and lead, and can be recycled after several years to meet the requirements of green building materials.

(4) Sponge sealing strip profile has a small proportion (only 0.9-0.95).It seems that the purchase unit price is high and the actual use cost is low.

Characteristics of Sponge sealing strip profile

1) Sponge sealing strip profile is light in volume, strong in expansion and does not absorb water (instead of traditional three-oil four-felt, bituminous fir board and other materials).The product is environmentally friendly, easy to construct, and has excellent seepage, leakage and water sealing effect.

2) Sponge sealing strip profile is corrosion-resistant, aging-resistant, high and low temperature + 80 ~45 ~C non-flowing, non-deforming, non-brittle and long service life.

3) Sponge sealing strip profile has an independent open air bubble structure. The special joint plate has the appearance of honeycomb holes uniformly distributed. It can be bonded closely with cement/sealant without hairing to adapt to the change of natural expansion and contraction and enhance the expansion and water sealing effect of joint seal.
