Product Introduction

The Compression Set Apparatus is a laboratory testing instrument designed to evaluate the permanent deformation of rubber and elastomeric materials after they have been held under compression. Specimens are compressed to a fixed deflection for a set period and then released, and the amount they fail to recover is measured, giving a reliable indication of sealing performance and long-term elasticity.

Key Features

• Compression Set Evaluation: Measures the permanent deformation of rubber specimens after prolonged compression.
• Constant Deflection Loading: Holds specimens at a fixed compression using spacers between the plates.
• Multiple Specimen Testing: Holds several specimens in a single test for comparative evaluation.
• Repeatable Testing: Provides consistent compression conditions for comparing materials and batches.
• Robust Construction: Designed for regular laboratory and quality control testing.
• Wide Material Compatibility: Suitable for rubber, elastomers, seals, gaskets, and flexible components.

Technical Parameters

Applications

Rubber & Elastomers

The apparatus is used to evaluate how well rubber and elastomeric compounds recover after prolonged compression, and to compare the performance of different compounds.

Seals & Gaskets

It supports testing of seals, gaskets, and O-rings, where the ability to keep their shape and sealing force over time is critical.

Automotive Rubber Components

The instrument can be used to assess rubber parts such as mounts, bushings, and sealing components that stay under load in service.

Industrial Rubber Products

It helps evaluate the long-term compression behavior of rubber sheets, pads, profiles, and other industrial rubber products.

Quality Control & Research

The apparatus is suitable for compound development, material comparison, batch-to-batch consistency checks, and routine quality control testing.
