Bio Polyol 350 EW (Castor Oil Based)

Description

Bio Polyol 350 EW (Castor Oil Based) is a renewable polyurethane polyol derived from natural castor oil. With an equivalent weight of 350, this bio-based polyol is specially designed for flexible and elastomeric polyurethane systems.

Compared to lower equivalent weight grades, this grade of castor oil based polyol improves flexibility, elongation and impact resistance while maintaining strong chemical and mechanical properties. It is widely used in industrial PU coatings, elastomeric sealants and specialty polyurethane applications requiring movement tolerance and durability.

As a castor oil based bio polyol, it supports sustainable formulation development without compromising on industrial performance.

Why Choose Bio Polyol 350 EW (Castor Oil Based)?

Firstly, polyurethane formulators prefer Bio Polyol 350 EW when they require a balance between flexibility and structural performance. Because it is derived from renewable castor oil, it supports sustainable product development while still delivering reliable mechanical strength.

Moreover, this grade performs exceptionally well in applications where substrate movement, crack bridging and long-term durability are critical. As a result, manufacturers of elastomeric coatings and sealants select this particular grade for its consistent quality, industrial compatibility and stable performance across varying environmental conditions.

Applications of Bio Polyol 350 EW (Castor Oil Based)

This Polyol with 350 Equivalent Weight is used in:

• Flexible polyurethane coatings
• Elastomeric floor coatings
• Joint and expansion sealants
• Protective coatings for concrete and metal
• Crack-bridging PU systems
• Electrical and electronic encapsulation

Therefore, its elastomeric properties make it highly suitable for systems exposed to thermal expansion, vibration and continuous mechanical stress.
