Light Yellow Liquid Blend Polyol For Rigid Polyurethane Foam Production With 245FA Blowing Agent For The Continues Sandwich Panel
JYP-241 for the continues sandwich panel
Product Introduction
JYP-241 is made from Polyether Polyols, catalyst, silicone oil and other additives with blowing agent 245FA.
JYP-241 has good mixing performance and is suitable for continuous sandwich panel production process.
It has stable foaming, excellent fluidity and flat surface. The foam produced by the combination of polyether and polymerized MDI has better thermal insulation performance and low temperature dimensional stability.
The finished products enjoy B1 level fire resistance.
