Cold resistance: It can be used at -20 °C. The lower the temperature, the stronger the tensile force, but the durability is reduced.
Water resistance: Maintain 50% tension in water and fully recover after drying.
Drug resistance: alkaline soda 50%, ammonia 28%, hydrochloric acid 2.5%, nitric acid 3.5% or less can still play a role.
