What is Rubber Contract Manufacturing and Elastomer Contract Manufacturing?

Rubber contract manufacturing or elastomer contract manufacturing is the industrial process through which rubber compounds are mixed, processed or molded according to customer technical specifications. This service allows manufacturing materials ready for vulcanization or finished parts with total quality control.

At Grupo Everest, each process is digitally controlled in power, time and temperature, guaranteeing total reproducibility and an optimal balance between physical properties and cost.

What is Uncured Rubber or Crude Rubber?

Uncured rubber, also known as crude rubber, is the processable base before curing. It is used when the customer requires a flexible, adaptable and easily processable material. It can be delivered as rubber fresh from the mill or in anti-adhesive sheets, to facilitate handling and storage without adhesion.

Advantages of Everest Uncured Rubber

  1. High plasticity and excellent performance in molding processes.
  2. Anti-adhesive finish that prevents surface contamination.
  3. Control of hardness, viscosity and density in each batch.
  4. Delivery with Quality Certificate and laboratory analysis.

Uses and Applications of Uncured Rubber and Contract Manufacturing

Elastomer contract manufacturing and uncured rubber are key in industries demanding mechanical resistance, chemical stability and dimensional precision. Their versatility allows application in molding, injection, extrusion and other industrial processes.

At Grupo Everest we develop compounds of silicone, EPDM, neoprene, nitrile (NBR) and polyurethane, adjusted in hardness, density and thermal resistance to guarantee reliable and durable performance.

Industrial applications

Automotive

Manufacturing of seals, gaskets, anti-vibration mounts, cable glands and retainers. Rubber contract manufacturing offers elasticity and resistance to oil, ozone and temperature, complying with international OEM specifications.

Construction and Infrastructure

Use in expansion joints, elastomeric bridge supports, structural sealants, acoustic and anti-vibration barriers. Uncured rubber allows manufacturing profiles and plates with anti-slip properties and great durability against weathering.

Oil, Gas and Energy

Development of electrical insulators, protective coatings, hydrocarbon-resistant seals, high-pressure gaskets and insulating covers. Our compounds formulated with NBR, EPDM and neoprene offer stable performance when in contact with oils, gases and solvents.

Medical and Appliance Sector

Production of silicone gaskets, precision molded parts, dielectric insulators, dampers and compression seals. Industrial grade silicone and polyurethane guarantee thermal resistance, flexibility and compatibility with sanitary regulations.

Railway and Maritime Industry

Manufacturing of dampers, fenders, watertightness joints, cushions and elastomeric supports. Our materials offer energy absorption and protection against impacts and vibrations.

Mining and Agricultural Industry

Pulley coatings, rollers, sealing gaskets, abrasion-resistant joints and machinery protectors. Crude rubber formulated with reinforcing additives guarantees longer service life under extreme conditions.

In summary, elastomer contract manufacturing optimizes production efficiency and ensures constant quality control. At Everest, more than 60 years of experience support us to accompany each client from formulation to delivery of material ready for vulcanization.

Rubber Contract Manufacturing and Industrial Mixing Processes

We have two complete mixing lines: one for black compounds and another exclusively for color products. Each variable of power, time and temperature is digitally monitored to guarantee total uniformity.

Available presentations

  1. Rubber in anti-adhesive sheets
  2. Rubber fresh from the mill
  3. Calendered sheets or rolls
