What's the difference between Oriental Yuhong and 74 1?

Compared with 74 1, 74 1 is superior in the following aspects:

1, excellent waterproof performance: good quality, excellent tensile strength, large elongation and good chemical stability.

2. Long service life: excellent weather resistance, aging resistance and excellent stability, which reduces the use of waterproof materials in a certain period of time and indirectly reduces resource consumption.

3. Efficient construction: super easy to construct, helping the master to reduce the construction difficulty.

Supplement:

Oriental Yuhong popular 300SBS modified asphalt waterproofing membrane is made of styrene-butadiene-styrene (SBS) thermoplastic elastomer as modifier, polyester tire base fabric as reinforcement layer, and polyethylene film (PE) as thermal insulation material on the surface.

Oriental Yuhong modified coil 74 1 is made of rubber modified petroleum asphalt as the impregnating surface, polyester fiber non-woven fabric, yellow linen, glass fiber felt and other materials. Using plastic film as anti-sticking isolation layer, it is made through the processes of material selection, batching, co-melting, impregnation, composite molding, curling and so on.
