KRAIBURG enhances its extremely soft TPEs

KRAIBURG TPE is introducing extremely soft thermoplasticd elastomers (TPEs) to meet increasing demand. The enhanced product is a further development of existing supersoft TPEs and has been adapted to new applications and requirements.

Since the range of applications is steadily increasing, there is a strong demand for very soft, tough and durable materials. From orthopedic appliances and bicycle equipment through to lids for cosmetics , the fields of application are as diverse as the specific requirements for the material itself. KRAIBURG TPE’s new series of extremely soft TPEs satisfies the current standards and regulations. All three compounds of the NEXT GENERATION Supersoft TPEs are being combined under the new name THERMOLAST S.

The new generation of supersoft TPEs has been developed on the basis of customer feedback and so the new compounds combine established properties with new practical requirements. The extremely soft TPEs have a pleasant, soft surface similar to human skin. This touch quality is a result of the low hardness range of 30–50 Shore 00 or 45–70 VLRH (very low rubber hardness). The materials’ substantially reduced tendency to oil out, for example, enables high-quality gel pad applications and optimizes ejection of the finished parts during processing.

Excellent mechanical properties and outstanding compression set at room temperature satisfy users’ requirements. The materials can be processed by injection moulding and 3D printing, playing to their strengths in both processes. In addition, the compounds have all necessary approvals and meet all necessary standards, so that they can be used immediately. For example, they have been tested in accordance with ISO 10993-10 (skin irritation). The product’s good skin compatibility also makes it outstandingly suitable for paramedical applications such as orthopedic appliances that do not necessarily require medical approvals.

The three NEXT GENERATION Supersoft TPEs are available in a translucent version as standard, and transparent compounds with hardnesses of up to 25 VLRH can also be supplied. The non-sticky granules can also be individually custom-coloured on request.
