POLYVEST® for Mechanical Rubber Goods (MRG)

Unlocking Versatility: POLYVEST® as the Ultimate Reactive Plasticizer for MRG's

POLYVEST® products are highly versatile and serve as effective reactive plasticizers for mechanical rubber goods (MRG). Due to its rubber-based composition, POLYVEST® integrates seamlessly into the rubber matrix of MRG compounds, ensuring excellent compatibility and performance.

Benefits for MRG Applications:

Also suitable for use in recycled rubber applications (e.g. playground mats)
Can be used for both sulphuric and peroxidic cross-linking in EPDM compounds
Enhances dispersibility of inorganic fillers
Increases elasticity and resistance to deformation
Reduces vulcanization time while improving tensile strength and compound viscosity

Elevate Your Rubber Formulations with POLYVEST® MA

POLYVEST® MA 75 is a specialized adduct derived from low molecular weight 1,4-cis liquid polybutadiene, functionalized with maleic anhydride. This unique formulation features randomly distributed succinic anhydride groups along the polymer chains, enhancing the polarity of the originally non-polar polybutadiene and making it more reactive for a variety of chemical processes. Additionally, we offer other maleic anhydride functionalized adducts with varying levels of maleic anhydride content and viscosity, such as POLYVEST® EP MA 100.

Benefits for MRG Applications:

Can be used for sulphuric cross-linking
Improves adhesion towards polar substrates
Improves elasticity
Higher resistance to deformation
Improve dispersibility of inorganic fillers in rubber compounds
Shorter vulcanization time, higher tensile strength and reduced compound viscosity in EPDM compounds

Rolled up black rubber sealant for elements of the car body, doors or trunk, for noise insulation, thermal and sound, preventing heat loss in the car interior. Sealing gasket for repair in a workshop.

POLYVEST® EP MV: The Versatile Low Viscosity Polybutadiene

POLYVEST® EP MV is a stereospecific, low viscous and unsaponifiable liquid polybutadiene manufactured using Ziegler-Natta polymerization. Due to its microstructure and outstanding combination of double bonds (higher vinyl, mid cis, no trans double bonds), this apolar and hydrophobic polybutadiene is a highly reactive and crosslinking binder providing benefits to a broad range of applications. This leads to a product with low viscosity, while simultaneously offering a suitable molecular weight.

Benefits for MRG Applications:

Can be used for peroxidic cross-linking in EPDM compounds
Hardness improvement
Better processing
Anti-bleeding effect
Low temperature resistance
