Plastic & Rubber

SEQENS develops custom solutions and ingredients for the most demanding industries such as aeronautic, construction, cosmetics, electronics, automotive and healthcare.

a range of polar modifiers

In this purpose, SEQENS offers a range of polar modifiers, MODENS BR and MODENS BS, enabling the production of styrenic block copolymers with enhanced properties used in various applications such as high performances tires production, asphalt paving modification, sealants, adhesives and medical devices.

Polar modifiers are especially used for SBS (Styrene-Butadiene-Styrene) and s-SBR (solution Styrene-Butadiene synthetic Rubber) polymerization.

These block copolymers consisting of a sequence of hard styrene blocks and soft butadiene blocks, are obtained through anionic polymerization technology which allows to produce tailor-made styrenic block copolymers by controlling polymer composition, microstructure, molecular weight distribution, degree and level of branching.

MODENS polar modifiers allow:

• A random incorporation of styrene to get the requested elastomeric performance characteristic
• To control the molecular weight distribution
• Microstructure modification with a high vinyl content to increase Tg of polymer for an excellent balance of handling, wed skid, traction and rolling resistance properties
