Chemical Industry
This specialist industry has to deal with demanding customers and strict regulations about safety, procedures and certificates. This is understandable because the chemical processes must be safe and controlled as effectively as possible.
Applications in the chemical and petrochemical industry can sometimes be critical. As well as broad chemical resistance, low and high temperatures are often of major importance. ERIKS has special compounds that meet these requirements. Are you having problems with your current application? If so, please contact us.
A logical consequence is that rubber compounds must meet exacting demands. ERIKS is ideally equipped for this, and has accumulated more than 50 years of experience in this industry.
