Hengshui Zhongxin Engineering Rubber Co., Ltd
China [CN] PZ Product Type of Water Swelling Strip is a new product by vulcanize, but unlike general rubber products, it has excellent resilience, extensibility and waterproof performance, the effect of stop water is more reliable than the average waterproof.
Features
1. It has excellent flexibility, extensible and waterproof performance, the rate of swelling in water can adjust between 100%-600%, remains rubber elasticity and extensible after expansion, the expansion rate is not influenced by the water quality.
2. It can play good waterproof performance in a wide temperature range.
3. It has excellent water resistance, chemical resistance and durability. It does not contain harmful substances, not have swelling precipitate and not pollute the environment.
4. It can make any shape according to the needs of user, and can make waterproof material of mixed type with the general rubber composite.
