BIOSOFT 750

Description

BIOSOFT 750 is a high-viscosity, biodegradable plasticizer obtained by controlled polymerization of rapeseed oil. This process increases the viscosity while maintaining the desirable properties of natural oils. BIOSOFT 750 enhances elasticity, flexibility, and compatibility in rubber formulations, particularly in heavy-duty compounds.

Applications

• Plasticizer and viscosity modifier for rubber blends (NR, SBR, EPDM, etc.)
• Tire compounds, technical rubber, seals
• Eco-friendly alternative to TDAE/DAE oils
• Suitable for heat- and oxidation-stable formulations

Key Benefits

• Excellent thickening and plasticizing properties
• Rapidly biodegradable (> 60% OECD 301D)
• Very high viscosity (675–825 mm²/s)
• Good oxidation and thermal stability
• REACH-compliant – very low PAH content
• Based on renewable raw materials
• Improves cohesion and filler binding in rubber

Storage and Handling

Store in tightly sealed containers in a dry and ventilated area. Avoid contamination and exposure to high temperatures. Refer to the Safety Data Sheet (SDS) for further information.
