Fire Retardant Additives for Thermal Runaway
Expandable graphite and Quarzwerke minerals can be used to enhance flame-retardant systems for EV safety.
HPF Quarzwerke has been extracting, processing and refining mineral for 135 years. Safe to say that they are experts in producing speciality fillers that enhance a huge variety of chemical products. For a full list of the minerals available please see the product listings below the company overview video. Aside from offering these grades in a variety of controlled particle size distributions, HPF is also able to add surface treatments to the materials in order to optimise their performance with a broad scope of chemistries.
Typical performance enhancements include increased rigidity, tuning of other mechanical properties like tensile strength, improved thermal conductivity, reduced warpage, lower coefficient of linear thermal expansion, improved scratch resistance, reactive transmission and opacity to EM radiation, tuning dielectric properties, improved barrier properties, corrosion protection, weather resistance, improved transparency, electrical insulation and decorative properties. See the video below for a high-level overview of the HPF product offering.

A brief introduction into the world of thermoplastics and the additives that can be used to adjust and specialise them.
Abrasives, such as Kaolin can be used in the car care industry to provide physical surface preparation, or polishing, and cleaning, aiding in the levelling of a clear coat layer.
Thermally conductive fillers such as SILATHERM® from Quarzwereke and Boron Nitride from 3M can increase the thermal conductivity of polymers.
