HIGH ELASTICITY AND STABILITY FOR LONG LASTING SOLUTIONS
A low modulus sealant is defined as an elastomeric material with a modulus at 100 % elongation of up to 0.4 MPa. This property can be obtained simply by the addition of an appropriate plasticizer. However, being non-reactive and not chemically anchored into the formulation, the plasticizer product can in turn have negative effects on properties like the elastic recovery.
Polymer ST 77
Polymer ST 77 is free of phthalates and is highly recommended for demanding applications where a balanced stress-strain behavior is re-quired as in transport and assembly applica-tions. Examples for the use of Polymer ST 77-based formulations are the assembly of superstructural parts, bumpers, etc. Mechanical fastening is often avoided as it could cause damage to the materials used. In addition, it could negatively affect the design.Product Datasheet (EN) Product Datasheet (DE)
