Two Mixing Lines Supporting Development and Production
A kneader mixing line and a Banbury mixing line support compound development and production. Project acceptance depends on formulation, materials, quality criteria, volume, and scheduling.

Rubber types we work with
Material Categories for Different Performance Requirements
Compare Rubber Material Categories
| Material | Material name | Characteristics and typical uses |
|---|---|---|
| NBR | Nitrile Butadiene Rubber | Often selected for resistance to oils, fuels, greases, and selected chemicals. Typical applications include seals, gaskets, hoses, and automotive or industrial components. |
| EPDM | Ethylene Propylene Diene Monomer | Known for resistance to weathering, ozone, water, and elevated temperatures. Typical applications include weather seals, gaskets, hoses, roofing or construction components, and outdoor products. |
| NR | Natural Rubber | Offers high elasticity, tensile strength, resilience, and dynamic performance. Typical applications include vibration-control products, industrial rubber goods, and mechanically demanding components. |
| BR | Butadiene Rubber | Provides high resilience, abrasion resistance, flexibility, and good low-temperature performance. BR is commonly used in blends where dynamic properties and wear resistance are important. |
| SBR | Styrene Butadiene Rubber | A versatile general-purpose elastomer offering balanced abrasion resistance, processability, mechanical performance, and cost efficiency. |
| IIR | Butyl Rubber | Known for very low gas permeability and good resistance to moisture, weathering, and many chemicals. It is commonly considered for sealing, air-retention, damping, and environmental-protection applications. |
| VMQ | Silicone Rubber | Offers a broad service-temperature range, flexibility, weathering resistance, and useful electrical properties. Grade selection must consider the specific fluid, chemical, regulatory, and mechanical requirements. |
Compound-development process
From Technical Requirements to Consistent Production Quality
Development stages are adapted to the compound, test requirements, and production arrangement.
Explore the Compound-Development Process
- 01
Define Requirements
Understand the application, operating environment, processing conditions, and target performance.
- 02
Develop the Formulation
Select or develop an appropriate material formulation around the agreed requirements.
- 03
Prepare a Sample or Trial
Prepare and evaluate laboratory or production samples as appropriate to the project.

Test and Adjust
Review physical properties and process behavior, then refine the formulation where required.
- 05
Standardize Criteria
Agree the relevant quality criteria and production controls to maintain consistent quality.
- 06
Move to Production
Confirm commercial-production, packaging, documentation, and delivery requirements.
Toll Mixing
Have a Formulation Ready? We Can Mix It for You.
We review your formulation, processing instructions, volume, and quality criteria before confirming mixing feasibility.
Material supply, scheduling, packaging, and logistics are agreed with our manufacturing team.

Frequently asked questions
Before You Start a Compounding Project
Commercial terms, material arrangements, scheduling, and documentation are confirmed for the specific project.
01What Information Is Needed to Develop a Custom Compound?
Start with the application, operating environment, processing method, target properties, applicable specifications, expected volume, and any existing benchmark or sample. Our team will identify any additional information needed during the initial review.
02Can Chemindo Work From an Existing Compound or Physical Sample?
An existing formulation, compound, benchmark, or physical sample can be included in the feasibility review. The development approach depends on the available information, target properties, materials, and processing requirements.
03What Is the Difference Between Custom Compounding and Toll Mixing?
Custom compounding begins with application and performance requirements and may include formulation development and evaluation. Toll mixing supports customers who provide a formulation for mixing.
04Who Supplies the Materials for Toll Mixing?
Material supply, handling, packaging, scheduling, and logistics are discussed directly with the manufacturing team for each project.
05Can Chemindo Source a Missing Ingredient?
Potential sourcing support is evaluated case by case based on the required material, availability, suitability, and the proposed commercial arrangement.
06What Testing and Quality Documentation Can Be Provided?
Testing, acceptance criteria, production controls, and supporting documentation are defined according to the compound, application, agreed control plan, and project requirements.
07How Is Confidential Formulation and Project Information Handled?
Customer formulations, specifications, samples, and project information are handled through controlled internal processes. Any formal confidentiality commitment can be documented contractually.
08Can Chemindo Also Manufacture the Finished Rubber Component?
Chemindo can evaluate finished rubber-product requirements, including available drawings, samples, specifications, tooling, quality criteria, and expected production volume.
