How We Produce Custom Coloured Rubber Compounds for Moulded Rubber Parts
Behind every high-quality coloured rubber product is a reliable and consistent rubber compounding process.
To meet the growing demand for customised rubber components in different colours, we have established a dedicated coloured rubber compounding workshop for the development and production of custom rubber compounds.
The dedicated workshop allows us to control the rubber mixing process more efficiently and provides greater flexibility when developing compounds in different colours and specifications.
Why Is Rubber Compounding Important for Coloured Rubber Products?
Rubber compounding is an important part of the manufacturing process because the compound directly affects the performance, appearance and processing characteristics of the final rubber product.
A properly formulated rubber compound can help achieve the required combination of:
Rubber hardness
Elasticity
Tensile strength
Wear resistance
Temperature resistance
Weather resistance
Chemical resistance
Colour appearance
Processing performance
For coloured rubber moulded parts, colour selection needs to be considered together with the required physical and performance properties of the rubber compound.
What Equipment Is Used in Our Rubber Compounding Workshop?
Our dedicated coloured rubber compounding workshop is equipped with production equipment designed to support efficient and consistent material mixing.
The main equipment includes:
75L Internal Mixer
22-inch Open Mixing Mill
Automatic Lifting System
The internal mixer is used for the initial mixing and dispersion of rubber and compounding ingredients. The open mixing mill is then used for further processing and adjustment of the rubber compound.
The automatic lifting system helps improve material transfer and reduce unnecessary manual handling during production.
How Do We Produce Custom Coloured Rubber Compounds?
The rubber compounding process starts with selecting the appropriate base rubber and compounding ingredients according to the required product performance.
Colouring materials are then incorporated into the rubber compound during the mixing process.
Depending on the application, the compound can be adjusted to achieve the required balance between colour appearance and rubber performance.
The general process includes:
Raw material selection
Rubber and ingredient weighing
Internal mixing
Open mill processing
Colour and compound adjustment
Material inspection
Preparation for rubber moulding or further processing
The exact formulation and processing parameters depend on the rubber material, colour and application requirements.
What Colours of Rubber Can We Produce?
We can produce rubber compounds in a wide range of colours according to customer requirements.
Common colours include:
Red
Blue
Green
Yellow
Orange
White
Grey
Black
Brown
Custom colours
For projects requiring a specific colour, customers can provide a RAL number, Pantone reference, colour sample or other colour specification for evaluation.
Colour matching can be discussed according to the requirements of the finished rubber component.
Can Coloured Rubber Maintain Its Required Performance?
Yes. The objective of custom rubber compounding is not only to achieve the required colour but also to maintain the physical and functional properties required for the application.
Depending on the product specification, the rubber compound can be developed around requirements such as:
Shore hardness
Tensile strength
Elongation
Compression set
Tear resistance
Abrasion resistance
Temperature resistance
Ozone and weather resistance
Oil and chemical resistance
The final compound selection depends on the application and the performance requirements of the rubber component.
What Rubber Materials Can Be Used for Custom Coloured Parts?
Different rubber materials can be considered depending on the application.
Common elastomers include:
EPDM
NBR
Silicone
Neoprene (CR)
Natural Rubber (NR)
FKM
Other specialised rubber compounds
Each material has different properties and application advantages. Material selection should therefore be based on the working temperature, chemical exposure, mechanical requirements, outdoor environment and other service conditions.
What Are Custom Coloured Rubber Parts Used For?
Coloured rubber components can be used in many industries where both functional performance and visual identification are important.
Typical applications include:
Automotive components
Industrial machinery
Electrical equipment
Electronic products
Sealing components
Rubber gaskets
Rubber washers
Rubber feet
Rubber covers
Vibration isolation components
Consumer products
Equipment identification components
Different colours can also be used to help distinguish components, improve product appearance or match the customer's existing product design.
Why Have a Dedicated Coloured Rubber Compounding Workshop?
A dedicated compounding workshop gives us greater flexibility when developing and producing customised rubber compounds.
It allows us to better manage:
Colour development
Material mixing
Compound consistency
Production efficiency
Material handling
Custom compound requirements
For customers ordering coloured rubber moulded parts, in-house compounding capability can also provide better coordination between rubber compound development and final moulded product production.
Custom Coloured Rubber Compounding for OEM Projects
We support OEM and custom rubber projects where customers require specific colours, materials, hardness or physical properties.
If you have a new coloured rubber component or an existing product that requires colour matching, you can provide:
Technical drawing
Physical sample
RAL colour number
Pantone colour reference
Required Shore hardness
Rubber material
Application requirements
Annual or order quantity
Our team can review the requirements and determine a suitable rubber compounding and manufacturing solution.

Frequently Asked Questions
What is rubber compounding?
Rubber compounding is the process of combining base rubber with selected additives, fillers, curing agents, pigments and other ingredients to achieve the required physical and processing properties.
Can you make rubber in custom colours?
Yes. We can develop coloured rubber compounds according to customer requirements. RAL numbers, Pantone references or physical colour samples can be provided for colour evaluation.
What colours of rubber are available?
We can produce common colours such as red, blue, green, yellow, white, grey and black, as well as customised colours based on customer requirements.
Can coloured rubber maintain the same performance as black rubber?
Coloured rubber can be formulated to meet specific performance requirements. However, the final properties depend on the rubber material, formulation, pigments and application conditions.
What rubber materials can be used for coloured rubber products?
Depending on the application, coloured compounds can be developed using EPDM, NBR, silicone, CR, NR, FKM and other suitable elastomers.
Can you match a customer's RAL or Pantone colour?
Yes. RAL and Pantone references can be used as a starting point for colour development. A physical colour sample may also be provided for evaluation.
What equipment do you use for rubber mixing?
Our dedicated coloured rubber compounding workshop includes a 75L internal mixer, 22-inch open mixing mill and automatic lifting system to support the rubber mixing and material handling process.
