CAI Performance Additives announces a slate of new products which includes ST-LST5350 and ST-LST0850, two proprietary light stabilizing agents.
They are extremely low VOC additives, meaning compounders can deliver light stabilization for their customers without worrying about inducing smell or surface bloom of VOCs.

Additives' Applications

These additives are particularly useful in durable applications like automotive parts that need to withstand long periods of light exposure. Unlike traditionally compounded light stabilizers, ST-LST0850 and ST-LST5350 are produced through a proprietary reactive process with no heat-history present when used by compounders. No dust or liquids need to be handled.

CEO Richard Marshall says, “The simple addition of this masterbatch can add huge value to your customers with superior resistance to clouding or fading surface qualities in final products. These new ST-LST products are in a unique pelletized form, so they can be added straight to the hopper, unlike other liquid poured solutions that are process-intensive.”
ST-NST5350 and ST-LST0850 are highly effective in PP, PE & TPO compounds. Benefits include:

• Using polypropylene as a carrier, ST-LST0850/5350 is based on porous polymers to load and deliver additives with maximum efficiency and low VOC

• Does not create VOC and odors as some conventionally compounded light stabilizers

• Dust-free delivery makes ST-LST0850/5350 easy to feed while maintaining excellent dispersion

• High efficiency maximizing light stabilization while maintaining material properties
