Glass fiber compositions are provided in the form of mats comprising a binder of thermoplastic polymer or other non-hazardous insulation material which resists high temperatures such as 2,000° F. for long periods. A binder for a fiber insulation mat utilizes a high molecular weight resin polyacrylic acid polymer mixed with a catalyst such as sodium hypophosphite and triethonal to provide a bond. A silicone provides water repellency, a surfactant controls surface tension, and ammonia or an acid adjusts the pH and a silane. |
