Kraiburg TPE new compound highlights excellent adhesion and UV resistance

This year Kraiburg TPE launched the new Thermolast K compound, which is mainly used in automotive applications such as EPDM window trim and sealing profiles, molded TPE corner joints and end elements
.
In addition, a series of new thermoplastic elastomers have been introduced, especially TPE that has excellent adhesion and UV resistance in the two-component application of ethylene propylene diene monomer rubber (EPDM) .
Window decoration and sealing profiles made of EPDM with molded Thermolast K corner joints and end elements .
 The automotive industry is the largest and fastest growing market for thermoplastic elastomers (TPE) .
New applications for automotive door and window sealing require dimensionally stable corner joints and end components .
At present, styrene-butadiene compound (SBC) and cross-linked thermoplastic vulcanizate (TPV) have been realized .
However, the cost-effectiveness of TPV is limited, especially for window decorations, because of various factors in the manufacturing process .
The EPDM adhesive series from Kraiburg TPE is a good alternative with high added value .
The new TPE series combines excellent weather resistance and adhesion with extruded and foamed EPDM profiles .

In order to reduce the cooling and circulation time of the two-component elements, the minimum injection temperature of the TPE solution is also required .
  AD / EPDM / UV series in conjunction with optimal adhesion properties and resistance to ultraviolet radiation durability and hardness of 70 Shore A thermal effect to meet all these requirements .
Compared with other materials, these special TPE products show excellent stability

 

















.
EPDM profiles are neither compressed nor broken or deformed.
The compound has uniform color fastness with EPDM, and there is no tendency for phase adhesion or phase separation
.
  Kraiburg TPE has tested the applicability of the new material in comprehensive adhesion, outdoor exposure and thermal aging tests .
And the processing performance and stability are optimized in close cooperation with the machine tool and mold manufacturers .
Tests have shown that the cleanliness of the EPDM rubber contact surface and TPE is of the utmost importance in these two component elements, and the freshly cut sealing profile can produce the best adhesion .
  AD/EPDM/UV technology has been tested by several customers in the automotive industry .
