Rubber Plasticizers & Additives

High-Performance Ester Plasticizers for Modern Rubber Compounding

NiMAC offers a comprehensive portfolio of ester-based rubber plasticizers and performance additives designed for a wide range of elastomers including CR, NBR, ACM, AEM, and ECO. These solutions are widely used in critical industries such as automotive, industrial hoses, footwear, conveyor belts, gaskets, CVJ boots, and O-rings.

Performance Benefits

  • Reduces melt viscosity to improve processing
  • Modifies mechanical and thermal properties
  • Acts as an effective filler compatibilizer
  • Improves aging resistance and long-term durability

Glyplast® Plasticizers

The Condensia Glyplast® plasticizer esters are engineered for low toxicity, low volatility, excellent solvating ability, high biodegradability, and outstanding compatibility with rubber compounds. These features allow them to meet stringent European and FDA regulations for food contact and environmental safety.

Rubber Plasticizer Categories

Polymeric Plasticizers

Saturated polyesters with a broad viscosity spectrum. Ideal as replacements for monomeric plasticizers when low volatility, low migration, and resistance to extraction are required. Also effective in providing flexibility at low temperatures in rubber products.

Monomeric Plasticizers

High-performance plasticizers and sustainable alternatives to phthalates. These compounds offer:

  • High solvating power and good workability
  • Low toxicity and environmental compatibility
  • Partial bio-based content

Available types:

  • Adipates: General-purpose, especially for low temperature performance
  • Polyether-esters: Excellent high-low temperature range balance
  • Sebacates: Designed for extreme low temperature flexibility
  • Trimellitates: For high temperature rubber applications
  • Phthalates: Cost-effective, general-purpose plasticizers

Specialty Additives

Antistatic Plasticizers: Aliphatic plasticizers designed to lower surface resistivity (approx. 10⁶ Ohm) by absorbing moisture. Available in:

  • External (Ionic)
  • Internal (Non-Ionic)

These plasticizers are food contact compliant under EU 10/2011.

Glyplast AS3 is a light coloured antistatic additive used in PVC and NBR. It's a food contact approved antistatic additive with plasticizing effect for non-black applications, such as white conveyor belts such as those used in food production.

Demolding Agent: External release agent ideal for hose mandrels. Offers excellent metal scavenger activity, low chemical oxygen demand (COD), and over 95% biodegradability. Recoverable by distillation for cost-effective reuse.

Glyplast 706/5 is a water diluteable concentrate for use as mould release in vulcanised rubber hose production where mandrels are used (EPDM, Acrylic or Vamac typically). The Glyplast 706/5 can be applied by spray or brush.

A demoulding additive for FKM (Fluorine Rubber) is available. This is for applications in FKM/FPM/Viton where solids such as Calcium Hydroxide are added and which can cause staining on the mould, which typically need a heavy acid or purging material to clean.
