New UV Absorber for Flexible Polyurethane Foam-JADEWIN UV1T


Flexible Polyurethane Foam is widely used material as supporting pad like in mattresses, upholstered furniture and car seats, pillow fillings and also shoulder pad of garment, benefiting from its low density , good breathability, Sound Absorption, thermal insulation, and perfect elastic resilience.

Depending on polyols, Flexible Polyurethane can be divided into two types, one is polyester type another is polyether type. The polyether flexible polyurethane has better elastic resilience than polyester ones. Thats why most of the support pad material like garments and sponge are polyether type.

However, polyether Flexible PU foam tend to go yellowing in processing and end application by limits of high foaming temperature and UV radiation.

Consequently, a new stabilizer of good thermal stability and UV Absorption for flexible polyurethane is becoming the focus of international companies.

Recently, Qingdao Jade New Material promoted a new UV Absorber JADEWIN UV1T by modifying the structure of common UV Absorber JADEWIN UV1, which is a has similar structure as JADEWIN UV1.

JADEWIN UV1T is Benzyl methyl ether in white powder ,overcoming defects of JADEWIN UV1 like color changing , bad heat stability and narrow UV absorption range.

The chart 1 show the TGA Comparison of JADWIN UV1 and UV1T, it show JADWIN UV1T has better thermal stability
