Paracril NBR grades are produced by cold and hot polymerization process. The cold process yields linear polymers with good processing characteristics and solubility in polar solvents. The hot polymerization process leads to more branching. Branching in the hot Paracril grades is more developed in the higher viscosity grades. The hot polymers offer improved green strength. &rosslinNed 3aracril N%5 grades are unique in processing and function.

Solprene

Arlatex is a water dispertion of copolymer of styrene- Butadene made by emulsion polymerization it could be carboxylic or not. It is used in applications such as carpets, textile and paper coating.


Arlatex

Styrene-butadiene block copolymers are polymerized in solution and present different structures, linear, radial and multiarm. They are free flowing materials that show different viscosities to adapt their properties to the multiple applications where they can be used in. Lower linear molecular weight grades offer very good flowability, are appreciated for their transparency and easy processability. Radial grades show higher melt strength, and offer higher mechanical properties with a high modification performance. Multiarm grades show a combination of low viscosity with temperature resistance. This performance make them suitable for a wide range of applications such as technical compounding, adhesives and sealants, bitumen modification for road pavements and waterproofing membranes. They are also used in shoe sole applications and polymer modification. They comply with different food contact applications. Typical physical aspects can go from fluffy crumbs to powder versions.


Calprene

Paraclean NBR has been developed to provide a low residue, fast curing grade of N%5. 3araclean grades are cold polymerized for best processing characteristics.


Paraclean

Offers excellent physical properties and outstanding processing characteristics due to the complete dispersion of the carbon black and processing oil in the polymer. Is recommended for use in tires, tread rubber and molded and extruded mechanical goods.
