Discoloration of Rubber Products

Manufacturer: We are manufacturer of latex casting and dipped products for medical applications. Very often, we encounter discoloration of our products. Please advise us how to overcome this problem.

John Woon (Senior Latex Consultant): Discoloration is an unwanted and undesirable change of colour of light-coloured rubber products especially white toy balloons. However, it is very often confused and misunderstood by many latex products manufacturers.

It can be caused by compounding formulation (ingredients), processing and storage or service conditions. Different causative factors would require different remedial actions to overcome them.

The following are the possible factors causing the discoloration of toy balloons:

1) Based Latex

2) Compounding Ingredients

3) Processing (curing and leaching)

4) Storage and Service Conditions
