KRAIBURG TPE: Thermoplastic Elastomers Suitable for Food and Mouth Contact

Published on 2020-04-21. Author : SpecialChem

TAGS:  Medical    

KRAIBURG TPE offers a complete portfolio of thermoplastic elastomers (TPEs) suitable for skin and mouth contact. These TPEs are relevant conformities and provide the expertise necessary for developing application-specific and customer-specific formulations. New compounds with excellent adhesion to polyamides complement the offer.

Food-compliant TPE Grades

KRAIBURG TPE’s THERMOLAST® K branded compounds meet requirements of the food and drug administration specified by Regulation (EU) 10/2011. The TPE specialist also provides compounds that comply with the Chinese GB 4806 regulations for food safety of materials. In addition, the range of types with food contact (FC) approval that show excellent peel strength and adhesion to hard thermoplastics has been expanded to include polar plastics. New in the portfolio:

  • FC/AD/PA series with outstanding tensile strength, elongation at break and wear resistance specially for multicomponent applications with polyamides (PA6, PA6.6 and PA12)
  • FC/AD1 series for composites with polyesters such as PET or PETG, polycarbonates, and ABS plastics, as well as blends of these materials.

Based on our well-established customer focus and many years of experience in the market, we have continuously diversified our product mix, so that we are now offering several TPE series that comply with food safety regulations and can be specifically tailored to address special application requirements,” says Lars Goldmann, Head of Sales Consumer at KRAIBURG TPE. “These also include UL-listed formulations for components that come into contact with lithium-ion batteries, as required for electric toothbrushes.”

Applications for Various End Products


Typical applications of KRAIBURG TPE’s compounds for the dental and oral hygiene market include manual and electric toothbrushes, interdental sticks and tongue cleaners, baby teething rings, soothers, teats for baby bottles, and razors and electric shavers.

Along with the new compounds with adhesion to polar plastics, the overall portfolio of THERMOLAST® K materials for this wide range of applications comprises four other established series suitable for composites with polyolefinic materials such as PP:

  • FC series with optimized cost-performance ratio and high flowability
  • FC/ht series for high transparency and outstanding depth effect of brilliant colors or effect pigments
  • FC/CS series with very good compression set, optimized chemical resistance (against mouthwash, special toothpastes, etc.) and enhanced mechanical strength – also suitable for bite-resistant baby teething rings
  • FC/HE/tl series for applications in translucent colors requiring extra high elasticity

These series are complemented by a wide variety of custom-engineered TPE compounds based on them, which are intended to meet individual requirements in special cases, such as cyclic load capacity (very long durability) or low tackiness. All of the materials can be colored individually and precisely – even effect colors and various transparent hues are possible. Precolored compounds are also available upon request.

Excellent Product Quality


In addition, KRAIBURG TPE ensures constant product quality in its materials with food contact approval by consistently tracing the raw materials used. This means that during selecting and purchasing of the raw materials, attention is already paid to whether the suppliers meet the requirements in relation to food contact and biocompatibility.

Furthermore, as recyclable materials, the TPE compounds meet the sustainability criteria of a raw material-efficient and environmentally friendly recycling economy.

KRAIBURG TPE sees itself as an innovative and reliable service partner for its customers, helping them to meet enhanced requirements and open up new sales opportunities by providing cost-effective and tailor-made thermoplastic elastomers,” emphasizes Mr. Goldmann. “Our comprehensive and flexible TPE portfolio for the dynamic dental and oral hygiene market underlines this commitment.”
