Description
ADSORB® P features a strong absorption of ultraviolet radiation in the 300-400nm region. It also has a high degree of photo-stability over long periods of light exposure. ADSORB® P provides ultraviolet protection in a wide variety of polymers including styrene homo- and copolymers, engineering plastics such as polyesters and acrylic resins, polyvinyl chloride, and other halogen containing polymers and copolymers (e.g. vinylidenes), acetals and cellulose esters. Elastomers, adhesives, polycarbonates, polyurethanes, and some cellulose esters and epoxy materials also benefit from the use of ADSORB® P.
Property
a)Odorless, don’t bring smell to polymers.
b)Insensitive to metal ion
c)Non-flammable, non-explosion, non-toxic, harmless to health.
d)Very high photo stability for its strong ability to absorb light especially in UV region (270~340nm)
e)Very stable to heat and can be used in plastic which require high processing temperature.
f)Hardly absorbing visible light, especially suitable for the colorless and the light-colored plastic products.
Toxicity & Safety
UV-P can be handled as an industrial chemical provided the following handing precautions are strictly observed: a) Wear gloves to avoid contacting with skin.
Maintain a clean and well-ventilated working area.
Wear goggles and face mask whenever dust is unavoidable to prevent irritation to the eyes and respiratory tract.
Package: Net 25kg paper drum or carton.
Storage: UV-P should be stored in a closed system and be kept in a dry and cool place.
IPG is focus on plastic fine chemical additives/ master batches with a global presence.
