EPDM blend for Profiles

Elaboration of Rubber Profiles for Automotive-industry

EPDM is extensively used in automotive applications and is favored to superior heat resistance, ozone resistance and weathering resistance. This study aims to elaborate rubber profiles for car windows and doors based on EPDM and EPDM/LLDPE blend formulations. Different prepared rubber compounds and vulcanizates were evaluated by determining the rheometric characteristics and physico-mechanical properties. The […] more...

Rubber Suspension in Sports

“Rubber” an indispensable Material for high Performance in Sports Application

The present paper deals with the development of a progressive rubber-suspension system as light weight construction substituting a combination of a steel spring and rubber bushing system for sports equipment application. The new developed rubber suspension element uses the V-element geometry with respect to well-known non-linear mechanical behaviour of rubber and the expected non-linear relationship […] more...

Rubber as Coating-Material

Chemical Modification of Poly (Vinyl Alcohol) with Starch/Natural Rubber and its Application for the Encapsulation of Urea Fertilizer

The objective of this work was to study the chemical modification of poly (vinyl alcohol) (PVA) with cassava starch (St) and natural rubber (NR) by using potassium persulfate (K2S2O8) as an initiator and its application in controlling urea release. The structure of the PVA grafted with St and NR was supported by ATR-FT-IR results. The […] more...

Prediction of Elastomeric Properties

A Proposition of constitutive Relationship of isotropic incompressible hyperelastic Material with limited Extensibility on the Basis of Gent’s Model

Elastic properties of rubber-like materials with limiting extensibility can be characterized by means of strain energy function and locking condition. One can show that the Gent’s model cannot be used for relatively large stretches and provides poor approximation of experimental data. The basic aim of the present paper is to propose a generalization of Gent’s […] more...
