Mineral raw materials for high-performance rubber plastics

Talk to our Industry experts

MAGNESIA has been your relia­ble partner for mineral com­pounds and inno­va­ti­ve light­weight fillers for over 40 years.

The rubber and pla­s­tics indus­try faces high demands: pro­ducts must be resistant, fle­xi­ble and durable – while simul­ta­neous­ly meeting strict safety and envi­ron­men­tal stan­dards. Whether for tires, tech­ni­cal molded parts, seals or special appli­ca­ti­ons: the choice of the right raw mate­ri­als is decisi­ve for quality and per­for­mance.

We deliver proven quality, tech­ni­cal know-how and tailor-made solu­ti­ons that opti­mi­ze your pro­duc­tion pro­ces­ses and improve your end pro­ducts. With our broad port­fo­lio, we support you in opti­mi­zing the mecha­ni­cal pro­per­ties of your com­pounds, con­trol­ling vul­ca­niza­ti­on and inte­gra­ting addi­tio­nal func­tions such as flame retar­dan­cy or weight reduc­tion.

Applications of our products in the rubber and placstics industry

Mineral raw mate­ri­als are indis­pensable com­pon­ents in the pro­duc­tion of rubber and plac­stics pro­ducts. Our pro­ducts are available in dif­fe­rent qua­li­ties and par­tic­le sizes – tail­o­red to your indi­vi­du­al requi­re­ments for purity, reac­ti­vi­ty and pro­ces­sing. They perform key func­tions such as:

  • Vul­ca­niza­ti­on aids for precise control of the curing process
  • Flame retar­dan­cy for increased safety in tech­ni­cal applications
  • Acid regu­la­ti­on & pH control for stable compounds
  • Filler & rein­force­ment to improve mecha­ni­cal properties
  • Pro­ces­sing aids for effi­ci­ent pro­ces­sing & homogeneity

Mineral raw materials proven in rubber and placstics applications

The com­bi­na­ti­on of mineral raw mate­ri­als and inno­va­ti­ve light­weight fillers opens up new pos­si­bi­li­ties in product deve­lo­p­ment. While classic com­pounds such as oxides, car­bo­na­tes and hydr­o­xi­des provide sta­bi­li­ty, vul­ca­niza­ti­on and flame retar­dan­cy, our MagS­phe­res® series offer addi­tio­nal bene­fits such as weight reduc­tion, impro­ved thermal insu­la­ti­on and opti­mi­zed sur­faces. This creates com­pounds that meet the highest tech­ni­cal requirements.

                      Why mineral raw materials are indispensable in the rubber and placstics industry

                      Mineral raw mate­ri­als are decisi­ve for the quality and func­tion­a­li­ty of rubber and plac­stics pro­ducts. They influence vul­ca­niza­ti­on, improve mecha­ni­cal pro­per­ties and provide addi­tio­nal func­tions such as flame retar­dan­cy or thermal insu­la­ti­on.

                      Magne­si­um hydr­o­xi­de is, for example, a halogen-free flame retar­dant cha­rac­te­ri­zed by high envi­ron­men­tal com­pa­ti­bi­li­ty. Calcium car­bo­na­te serves as a cost-effi­ci­ent filler and opti­mi­zes ela­s­ti­ci­ty, while zinc stea­ra­te as a lubri­cant and pro­ces­sing aid impro­ves the homo­gen­ei­ty of the compound.

                      As an expe­ri­en­ced partner to the rubber and plac­stics indus­try, MAGNESIA offers not only high-quality raw mate­ri­als but also com­pre­hen­si­ve service.
