HGC (High Gravity Compounds) are plastic materials with high specific gravity (density) greater than the base polymer. The use of this type of material allows obtaining details of the weight of metal, at the same time using the typical treatment of thermoplastics such as extrusion or injection, which facilitates the design of details, allows combining with other materials, and reduces production costs compared to metal elements. Composites are used in pipes, weights, ballasts, radiation shields, vibration-damping elements or in caps and plugs for cosmetics that emit high-aesthetics metal.

MB, concentrates for plastics

We offer compounding of concentrates for plastics adapted to individual customer requirements in terms of the type of base polymer (LDPE, HDPE, PP, PS and others), applications (injection, blow moulding, extrusion), active substance content and processing additives.

  • Flame-retarding MB based on halogen compounds and molybdenum oxide.
  • Filling MB: chalk, barium sulphate, sodium sulphate, magnesium oxide, talc
  • MB that colours TiO2
  • Drying MB on the basis of CaO
  • Other

Modification of entrusted materials

Modifications of entrusted plastics through the introduction of fillers, flame-retardants, lubricants - slips, foams, UV stabilizers, impact modifiers, other plastics or modifiers. Types of modifications:

  • Dry mixing of raw materials
  • Granulation on a single-screw extruder
  • Granulation on a co-rotating twin-screw extruder
  • Plastic densification, e.g. foil + granulation

All our compounds are thoroughly tested in the WWEKOCHEM’s laboratory in terms of rheological and mechanical properties. The customer receives all the required test results and full documentation, such as the TDS-technical data sheet and the MSDS-safety data sheet of a given substance/mixture. At the customer's request, we can also issue a food contact certificate and conduct tests in accredited external laboratories.
