What are the main characteristics of flame-retardant sealing strips?

Thermoplastic EPDM rubber sealing strip

This kind of seal is a new material developed in recent years on the basis of foreign introduction of technology and domestic independent development. It is mainly used for sealing automobile doors and windows. In recent years, it has been used for the construction of door and window seals.Its outstanding advantages are：

The performance and service life are similar to that of vulcanized ternary ethylene rubber sealing rods.

The processing energy consumption is lower than that of vulcanized ternary acetylene strips (the same as PVC).

It does not contain heavy metals such as halogen and lead, and can be recycled in a few years to meet the requirements of green building materials.

The specific gravity is small (only 0.9-0.95) and the clearance rate is high.The purchase unit price is high, and the actual cost of use seems to be low.

What are the product characteristics of flame-retardant sealing strips?

1) Light size, high tensile strength, non-absorbent (replacing traditional three-oil four-felt, asphalt fir and other materials).The product is environmentally friendly, easy to construct, impermeable, leak-proof, and has good water stop effect.

2) Corrosion resistance, anti-aging, high and low temperature resistance 80~-45, no flow, no deformation, no brittleness, long life.

3) It has a unique hole bubble structure, and the special seam board evenly distributes honeycomb holes without linting, closely binds to cement/sealant, adapts to changes in natural expansion and contraction, and improves the effect of seam sealing and expansion stopping.

The sealing elasticity and continuity are greatly strengthened than PVC rubber bands, but microwave vulcanization lines are required to be shaped. Therefore, the processing energy consumption is high, which is more than 20 times that of ordinary PVC processing. The product is non-recyclable and environmentally friendly. It is not a product advocated by the state.In addition, the specific gravity of this product material (above 1.4) is equivalent to PVC (low-end vulcanized ternary ethylene tape has a larger proportion), the warehouse clearance rate is similar to that of PVC tape, and the cost of use is relatively high, which is difficult for door and window companies to accept.The benefits of flame-retardant sealing strips：

1. Corrosion resistance, anti-aging, high and low temperature resistance 80~-45, no flow, no deformation, fragile, and longer service life.

2. Heavy metals that do not contain halogen and lead can be recycled after a few years, which meets the requirements of environmentally friendly building materials.

3. The specific gravity is small (only 0.9-0.95) and the clearance rate is high.

4. The product is environmentally friendly, simple construction, anti-leakage, anti-leakage, and good water stop effect.

5. The performance and service life are similar to that of vulcanized ternary ethylene rubber sealing rods.

6. It has an independent hole bubble structure, and the special seam board evenly distributes honeycomb holes without linting, and is closely bonded to cement/sealant to adapt to changes in natural expansion and contraction, and improve the effect of sealing and stopping the expansion of the seam.
