Pure gum is a full floating natural rubber. It resists most organic salts, ammonia, acids, and alkalis. It is the premier non-marking rubber part due to its supple, soft and excellent flexibility while under stress. This product is perfect for squeegee applications such as professional window cleaning equipment or machines which clean ice skating rinks. Another popular use is "drum practice pads." It also makes a great industrial skirting due to its excellent flexibility and high tensile strength. Pure Gum is a great choice for industrial applications which require a very flexible elastomer with great "rebound or bounce back" qualities.
