BNX® 1225 TPR is a pelletized blend of BNX® 1225 and a SIS (styrene-isoprene-styrene) thermoplastic rubber. BNX® 1225 is a synergistic blend of BNX® 1010 and Benefos® 1680. This blend of both a primary and secondary antioxidant provides excellent heat stability and antioxidation, with good compatibility with resins and excellent extraction resistance. The SIS (styrene-isoprene-styrene) thermoplastic rubber has a styrene content of 14%, diblock content of 12% and a melt index of 9.

Applications: BNX® 1225 TPR is a 45:55 blend of BNX® 1225 and a SIS thermoplastic rubber in a pelletized form. This product is used in the manufacture of hot-melt pressure sensitive adhesives (HMPSA) using single or twin-screw extruders. This unique product can also be used with sigma mixers to achieve a more uniform dispersion of the antioxidant in the HMPSA. BNX® 1225 TPR is compatible with other SIS thermoplastic elastomers such as Quintac® 3620, Kraton D1161P, Kraton D1193, Enichem ST-190, and Vector 4113.

Advantages:

• Accurate Dispensing in Loss-In-Weight Feeders (i.e. K-Tron) - uniform shape and size, pellets are durable enough for air conveying (will not break-up), high melt resistance / non-bridging or blocking

• Increased Processing efficiencies - reduced handling time, increased product dispersibility in twin screw extruders and sigma mixers, compatible with standard antioxidant metering equipment, minimal screw slippage, dry and dust free

• Reduced Health Hazards - caused by dust inhalation, caused by prolonged skin contact

• Reduced fire and explosion hazards - caused by electrostatic charge build-up, no powders
