Kraiburg has been a truck and bus industry leader for several decades. It has developed, produced, and supplied technical rubber and silicone compounds for truck parts since 1947. Examples of its high-quality and dependable products are thermoplastic elastomers (TPE) for a broad range of functions. These include automotive interiors, exteriors, and powertrains, along with the retreading of tyres. The company has proved its superiority as the major supplier to OE and aftermarket air spring manufacturers, thanks to its rubber technology that boasts longevity and stretches the operating life.
Importance of Kraiburg Rubber

- Side veneer (With varying strengths; dust or perforation)
- Rubber solution
- Profile filler strips
- Tread sheet
- Cushion gum (sheets or tread material strips)
- Different accessories
Cold Retreading
The Kraiburg collection for pre-cure retreading incorporates:
- Pre-cured treads
- Sidewall ‘cold’ veneer
- Rubber solution
- Bonding gum (sheets or tread material strips)
- Envelopes (inner and outer)
- Venting pads
- Tyre paint
- Release agent couplings
- Valves
Particularised compound for trucks
They are made for:
- Long-distance and urban traffic
- Building sites
- Quarries
- Trailer
- Special compounds
Thermoplastic Elastomers (TPE)
Otherwise known as thermoplastic rubbers, Thermoplastic Elastomers are compounds or copolymers that provide thermoplastic and elastomeric properties. TPEs exhibit thermoplastic features above their typical melt temperatures, making it easy to fabricate them into various units.
TPEs exhibit elastomeric behaviour when used in their temperature ranges. This is without cross-linking during the fabrication procedure. Besides, the procedure is irreversible, excluding the possibility of reprocessing or remoulding the products. TPEs are stretchable and can return to their almost-original shape compared to their more rigid counterparts. This comes with two advantages, a longer lifetime and enhanced physical range.
Interior TPEs
TPEs can be applied to truck interiors such as truck driver seats, truck door accessories, and more. Using TPE fosters attractive surfaces and enhances the soft-touch elements, as well as minimising rattling and creaking noises in damping elements. Kraiburg’s TPE solutions for low-emission interiors match the OEM requirements applicable to truck interiors.
Application Areas
- Shelf and floor mats
- Cupholders
- Thumb sliders/wheels
- Cable sleeves
- Damping and buffering elements
- Gearshifts
- Adjusting levers specialised for steering wheels and seats
- HVAC lamella sealings
- Door sill panels
Exterior TPEs
The company’s exterior TPEs have exceptional weather and UV resistance, perfect for exterior truck applications. This results in visually appealing and high-quality surfaces when applied.
Application Areas
- Window encapsulations
- Water deflectors
- Windshield cowl covers
- A/B/C pillar covers
- Window sealing systems (corner mouldings and end caps)
- Multi-component door sealings
- Roof rails base pads
- Antenna gaskets
- Steps
Properties
- Adhesion to PP, PC, ASA, PMMA, PC/ABS, and more
- Adhesion to EPDM and TPV
- Efficient processing in multi-component injection moulding
- Low internal mould pressure is achievable with long flow paths
Powertrain TPEs
Engine compartments grow more and more complex by the day, increasing their prices. The good thing is that Kraiburg gives an economical alternative. Their compound creations are developed particularly for the heavy truck industry and can be processed in multi-component injection moulding. Also, they showcase optimal long-term stability when exposed to extremely high temperatures, ideal for harsh climates and during contact with engine oils and grease.
Application Areas
- Mounting elements such as truck engine mounts
- Air duct elements, ventilation flap controls
- Grommets
- Battery seals
- Timing belt covers
- Tank recesses
- E-box gaskets
- Vibration control components in the transmission
- Sealings in oil management
Conclusion
Kraiburg rubber is comprehensively used in truck applications, from the tyres to the interiors. They are perfect for aftermarket parts for Japanese trucks, European trucks, and more—courtesy of their affordability and high-quality and long-life characteristics.
