Abstract
Balancing weights for a rim of a vehicle wheel are made from a balancing weight material, which comprises a hot melt adhesive based on Polyolefins or Ethylene-vinyl acetate (EVA) copolymers filled with a volume ratio between 35% and 75% of a high-density mass material like steel particles. This balancing weight material is heated such that it becomes a ductile and adhesive material, which can adhere to the rim and applied to the rim. After cooling off a solid and fixedly attached balancing weight has been made.

Balancing weight material for manufacturing of balancing weights, the balancing weight material comprising:
- a hot melt adhesive, where
- the hot melt adhesive comprises a filler of a high-density mass material,
- the high-density mass material further comprises milled or ground stainless steel particles with particle sizes with d50 values between 20 μm and 150 μm,
- the high-density mass material further has a volume fraction of between 35% and 75% relative to the balancing weight material, and
- the balancing weight material has a first melting temperature at which a surface of the balancing weight material will become adhesive.
Method for the application of a balancing weight to a mounting surface, the method comprising the steps of:
- a) providing a balancing weight material comprising a hot melt adhesive,
- the hot melt adhesive comprising a filler of a high-density mass material,
- the high-density mass material further comprising milled or ground stainless steel particles with particle sizes with d50 values between 20 μm and 150 μm,
- the high-density mass material further having a volume fraction of between 35% and 75% relative to the balancing weight material, and
- the balancing weight material having a first melting temperature at which a surface of the balancing weight material will become adhesive,
- b) heating the balancing weight material and/or the mounting surface to a temperature above the first melting temperature,
- c) applying the balancing weight material to the mounting surface, and
- d) cooling the balancing weight material to a temperature below the first melting temperature.
