Crompton is developing CaZn thermal stabilizer / lubricant one package, providing improved durability in hot, arid climates white fence and window profiles.
Low VOC heat stabilizers, Mark 6797 is a wire and cable sheathing, and general-purpose flexible extruded solid CaZn.
CaZn low haze solid heat stabilizer, a new tag 6790 is to substitute lead or BaZn stabilizer in the car interior.
The new design also provides improved performance is more environmentally friendly vinyl additives Request Crompton Corporation, Middlebury, Conn., the company's latest developments among low-VOC heat stabilizers for the flexible and rigid pvc-additive and impact modified character is rigid PVC.
Liquid heat stabilizer was originally developed as a general-purpose and flexible PVC in low VOC emissions. They have less than 10ppm phenol content, and their resistance to hydrolysis and free phenol form, adapted to their use of low-emission interior floors and car interiors. Recently, another advantage of these products have become apparent. They also have very low phosphorus content - 2.5%-compared3% according to conventional mixing 5% of liquid metal stabilizer. It has been found seeping high phosphorus content and poor printability issues. Higher oxidation, good clarity and better thermal stability than conventional mixing liquid metal. They also said: To provide good printability due to low plate out and finished well to survive in hot, humid weather during and warehouse storage. These stabilizers are expensive, but they can be used from 20 to 25% level (two to 3phr) lower than the conventional stabilizers in many applications.
Crompton is also developing a new ternary intermetallic (CaKZn) liquid. 2 to 3phr recommended usage levels, this agent has a significant thermal stability than conventional BaZn stabilizer compounds for clear and flexible non-filled wire and cable. Expected FDA approved for contact with food.
