good price high purity liquid oil material silicone l580 for flexible polyurethane(pu) foam
About Product
L580 is high efficiency silicone-polyol block copolymer used in the production of polyether polyol- based flexible polyurethane foams,L580 can be used in discontinuc ous foam production process(box foam) or in continuors process(slabstock).
L580 yields a regular emulsification of the raw materials and provic de the foam with the desired regular cell structure throught its nucleating strength.
L580 is compatible with most polyol pre-blends and its superior hy drolytic insures superior stability L580 is particularly recommended for flexible foams having a dens ity below 30 kgs/m3,Its efficiency is such that L580 allows the production of foams having a density ower than 15 kgs/m3 with very limited set back.

Product Details
Applications
1. Suitable for polyether type flexible foam production on all types of foam production equipment,
like streamline foaming equipment and box foaming process.
2. Excellent stability.
3. Wide breathablity profiles for different formulations.
4. Bring excellent results in medium density flexible foam production.
Handling
Avoid contact with skin and eyes. Avoid inhalation of vapour or mist. Keep away from sources
of ignition - No smoking. Take measures to prevent the build up of electrostatic charge.
Storage
Keep container tightly closed in a dry and well-ventilated place. Containers which are opened
must be carefully resealed and kept upright to prevent leakage. Store in cool place.
