German speciality chemicals company Lanxess has added a plant-based raw material variant to its Aktiplast PP product range. These processing promoters for polymer blends are used in the production of tyres and all kinds of technical rubber articles. Aktiplast PP-veg, which is based on renewable raw materials, was developed specifically in response to a customer requirement from Asia. In this way, the Lanxess Rhein Chemie business unit aims to enable rubber processors to reduce their CO2 footprint. An international tyre manufacturer from Europe has already expressed interest, says Lanxess.
Unlike the conventional product, Aktiplast PP-veg is manufactured only from vegetable oils. The proportion of renewable raw materials in Aktiplast PP-veg is around 90%, so that its CO2 footprint is significantly reduced. The starting point are raw materials made from the fruits of oil palms. They are ecologically more sustainable than coconut palms, rapeseed or sunflowers, as they provide by far the highest oil yield per hectare of farmland area.
The processing promoter is particularly suitable for polymer blends based on natural rubber. It reduces the viscosity of rubber compounds and significantly improves injection and extrusion behavior, also in combination with functionalised polymers. Depending on the compound composition, the product improves scorch behaviour, promotes vulcanisation and ensures easy demoulding without contamination of the mould.
