Dynasylan® for more stability in glass fiber products
Glass fibre products, such as endless glass fibres, chopped strands, mats, rovings, yarns, milled glass fibre, glass wool are used as reinforcing materials in plastics.
Glass fibre products such as mats are used as reinforcing materials in thermoplastics.
Dynasylan® improves adhesion and mechanical properties of glass fibers.
The strength imparted to the plastic by the glass fibre combined with silane-inducted excellent adhesion promotion provide high profile properties of the reinforced material.
Good heat and sound insulation
The natural glass surface shows poor adhesion to polymers, particularly in the presence of moisture. For this reason the glass surface is altered organophilic by a size or finish treatment. The essential components of the size or finish are our Dynasylan® products.
