BTA-736S offers high-impact efficiency with superior clarity and good resistance to crease whitening. BTA-753ER gives maximum toughness at ambient or low temperature in general-purpose opaque vinyl. Paraloid EXL-3300 series acrylic tougheners are for weatherable applications of engineering resins requiring good color retention. EXL-3330 offers good inherent thermal stability, resistance to uv degradation, and balance of toughness. EXL-3361 gives enhanced thermal stability and good balance of properties including colorability. Paraloid EXL-3600 series MBS tougheners for engineering resins give superior low-temperature impact resistance. EXL-3611 is a reactive toughener for nylon. EXL-3691A is a general-purpose toughener providing a balance of low-temperature impact resistance and modulus for engineering resins. The Paraloid series of specialty and multifunctional additives are designed for adding only one product to the blending operation. Paraloid KM-5450 and Paraloid KM-X100Pro contain impact modifier and processing aids. Paraloid multifunctional additives are blended in a liquid state and isolated into powder as one product. This ensures accurate ratios of the components and consistent performance.
DUPONT PACKAGING & INDUSTRIAL POLYMERS
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.
