Key Features & Analytical Properties
KLAREX RG 227 has the following features:
 Excellent dispersibility
 Improved processing characteristics
 High speed processing with smooth surface
 Improved dimensional stability and die swell
PRODUCT BROCHURE
KOHLENSTOFF® Carbon Blacks

2. Mechanical Properties of EPDM
Compound
 Tensile strength, % Elongation at break and
Modulus at various extensions of KLAREX
RG 227 are comparable to International
Competition delivering a dimensionally stable
surface. Due to its unique morphological
properties, KLAREX RG 227 is more resistance
to compression set. Lower compression set
provides more dimensional stability of the
product
Displays superior surface finish
 Lowest defects level of KLAREX RG 227 is one of
the outstanding properties based on size class
Processing: Rheometric Properties
 Low Mooney Viscosity of KLAREX RG 227 exhibits
faster and easier processing

Conclusion
 The compression set and modulus data of KLAREX RG 227 indicate improved product performance
in terms of shape retention during application.
 KLAREX RG 227 shows lower defect count in extrudate tape compared to International Competition
translating to superior surface finish and defect free profile.
 Irreplaceable morphology with low surface area and very high structure combination exhibits less
time for mixing with high loadability.
