Line of fluorochemical blowing agents includes Formacel Z-2 (HFC-152a), FDA approved for use in PS food service and packaging foams; Formacel S (HCFC-22) used in closed-cell polyurethane and polyisocyanurate foams; and Formacel Z-4 (HFC-134a) for polyurethane systems and appliance foams, and in PS insulating board.
Company's toughening technologies involve ethylene terpolymers, ionomers, and grafted polyolefins.
Ethylene terpolymers provide impact resistance over a broad temperature range, particularly at low temperatures, for various thermoplastics. In thermoplastics, ethylene terpolymers improve impact resistance of PVC, ABS, SAN, SMA, and PC. In PVC they offer improved weatherability and easier processing resulting from a reduction in melt viscosity. Weatherability is also improved in ABS.
Surlyn ionomer resins provide low-temperature impact properties in nylon 6 and nylon 66. In TPOs, ionomers enhance abrasion resistance and paintability.
In reinforced PP and PE compounds, Fusabond anhydride-grafted polyolefin modifiers improve toughness by increasing adhesion between reinforcements and the resin matrix. Fusabond N anhydride-grafted EP rubbers provide superior toughening in 6 and 66 nylon.
Elvaloy resin modifiers for PVC include grades suitable for impact modification. Products have an extremely high molecular weight (250,000), which makes PVC compounds more durable. Reportedly, they have near zero extraction and essentially zero volatility, migration, and exudation, and provide heat, oil and uv resistance. Have been used commercially for calendered, extruded and injection molded products. Applications include office chair mats, pond liners, single-ply roofing, automotive interior applications, upholstery, wire and cable insulation, floor tile, hose and tubing, and footwear. Available as free-flowing pellets and in powders.
