Specialty Elastomer Parts & Products
Introduction
At Eutsler Technical Products, our Custom Elastomer Compounding and Formulation Development program is the foundation of every high-performance product we deliver.
From the molecular structure of the polymer to the filler–curative balance, we design and control every variable to achieve optimal physical, chemical, and dynamic performance for your specific application.
With over 60 years of elastomer engineering experience, Eutsler combines materials science, processing control, and field performance data to create compounds that meet precise functional, environmental, and regulatory requirements—whether for oilfield isolation elements, aerospace seals, medical-grade components, or industrial vibration isolators.

Formulation Development Process
Application & Property Targeting
- Define environmental and mechanical requirements:
- Temperature, pressure, chemical exposure, and mechanical load.
- Key performance metrics (e.g., tensile, tear, elongation, modulus, compression set).
- Evaluate cost/performance optimization using polymer–filler–curative mapping.
Material Selection & Design
- Base polymer selection (single or multi-phase systems).
- Filler selection (carbon black, silica, clay, or specialty reinforcements).
- Plasticizer and softener optimization to control low-temperature flexibility.
- Curative system engineering (sulfur, peroxide, bisphenol, diamine, metal oxide, and phenolic).
- Integration of anti-degradants and stabilizers for oxidation, ozone, and UV.
Laboratory Compounding & Rheology Validation
- Small-batch two-roll mill.
- Rheometric testing (ASTM D5289) to characterize cure kinetics and scorch safety.
- Mooney viscosity (ASTM D1646) and processability analysis.
- Cure optimization using Arrhenius modelingand thermal cure profiles.
Material Testing & Qualification
- Tensile / elongation (ASTM D412)
- Tear strength (ASTM D624)
- Hardness (ASTM D2240)
- Compression set (ASTM D395)
- Heat aging (ASTM D573)
- Fluid immersion (ASTM D471)
- Specific gravity, modulus, rebound, and dynamic fatigue testing
- Custom chemical resistance and high-temperature exposure validation
Scale-Up & Production Transfer
- Transition from lab-batch to production mill mixing with controlled friction ratios, batch weights, and roll temperatures.
- Verification of batch rheology, Mooney viscosity, and color dispersion uniformity.
- Full traceability documentationlinking raw material lots to final compound code.
Performance Customization & Optimization
| Property Target | Control Mechanism |
|---|---|
| Hardness (Shore A) | Polymer-to-filler ratio, plasticizer content |
| Tensile Strength | Reinforcing filler type, crosslink density |
| Tear Resistance | Polymer chain structure, filler dispersion |
| Compression Set | Cure system, crosslink density control |
| Abrasion Resistance | Filler morphology, coupling agents |
| Thermal Stability | Curative system and antioxidant package |
| Oil & Fuel Resistance | Polymer polarity, acrylonitrile content |
| Rebound / Resilience | Plasticizer control, polymer backbone structure |
| Adhesion to Metal / Fabric | Reactive functional group integration |
| Gas Permeability | Polymer backbone and filler loading |
Formulation Control & Traceability
Each Eutsler compound is identified by a unique formulation code, linked to:
- Masterbatch design sheet (recipe, weight, filler content, polymer type).
- Process control records (mixing temperature, time, and torque).
- Rheometric cure data (reference torque and time-to-cure).
- QC mechanical properties for every batch.
All data is stored under our ISO 9001:2015-certified quality system, ensuring full reproducibility and compliance for regulated industries.
Advanced Compounding Techniques
- Multi-phase compounding for dual-hardness or layered materials.
- Reactive blending of polar and non-polar polymers for hybrid resistance.
- Nanofiller integration (silica, clay, carbon nanotube) for enhanced permeability resistance, tear and modulus improvements.
- Surface-functionalized additives to improve filler dispersion.
- Anti-static / conductive compounds for specialty applications.
Industry Applications
Eutsler’s custom compounds are trusted in critical sealing and dynamic systems across multiple industries:
- Oil & Gas: Packers, sealing elements, and isolation tools.
