Vspray-3 Environmental Blowing Agent Polyurethane Spray Foam Insulation Blend Polyols 200-300 mgKOH/g Hydroxyl Value
Vspray-3 is an eco-friendly polyurethane spray foam insulation blend using 245fa blowing agent. It delivers excellent thermal performance with ≤24 mW/(m·K) conductivity, ≥90% closed-cell rate, and ≥150 kPa compressive strength. Ideal for cold rooms, industrial pots, and pipeline insulation with 6-month storage stability.
Vspray-3 is an environmentally friendly spray blend polyols formulation that uses 245fa blowing agent instead of HCFC-141B. When reacted with isocyanate, it produces high-performance polyurethane foam with excellent insulation properties.
- Fine and uniform cell structure for consistent insulation
- Low thermal conductivity for superior energy efficiency
- Excellent flame resistance for enhanced safety
- Good dimensional stability at low temperatures
Ideal for various thermal insulation projects using spray technology, including cold storage rooms, industrial pots, and large-scale pipeline insulation systems.
