High Tear Strength Silicone Rubber

High Tear Strength Silicone Rubber are a group of silicones that are specially designed with a focus on mechanical and static strength in the presence of vulcanization agents such as DHBP and DCBP, and are used in parts with complex shapes and production of very large parts. These types of silicones are designed in such a way that they have a very good and higher elongation and tear resistance than normal silicones, and they can be used in the production process of molding and extrusion parts.

Features of High Tear Strength Silicone Rubber

High tear resistance
The percentage of elongation is high
Good tensile strength
Unique processability during extrusion
Good processability in molding
High thermal resistance
High transparency

Applications of High Tear Strength Silicone Rubber

Medical equipment sealant
Car silicone washers
Silicone sheets
Medical Equipment
Aviation industry
