Product Description

Colored Silicone Good Elongation Sponge Rubber Ball for Pipe Cleaning

Material DescrIption for silicone Sponge Rubber Ball

Silicone Rubber (Q, MQ, VMQ, PVMQ)

*Service Temperature
For Silicones the service temperatures are from -60 C to 225 C. Some special types can be used in extreme temperature up to 300 C and down to -100 C.
*Application
Silicone rubber performs well under environmental and temperature extremes. It is usually applied in automotive and aerospace industries where flexibility and longevity are important. It is also a suitable material for parts that need FDA approval for food handling equipment and appliances.

Product Introduction for Sponge Rubber Ball

Sponge Rubber Ball is especially suitable for various condenser copper tubes. Sponge Rubber Ball is also the most commonly used in power plants. Sponge Rubber Ball is always made of  natural rubber with foam and special additives. Standard Sponge Rubber Ball can be used in all kinds of equipment and water .
Sponge Rubber Ball is very effectively in removing biofouling and high viscosity biofouling. Sponge Rubber Ball is Suitable for stainless steel tubes and titanium alloy tube heat exchangers.

The standard appearance of Sponge Rubber Ball 
1. The air holes spread evenly on the surface of Sponge Rubber Ball ,and their size is basically similar ;
2, The depth of lack of rubber is less than 3mm on the surface of Sponge Rubber Ball .and the total area of lack of rubber is 10% less than the outside surface area;
3. The diameter tolerance of the sponge rubber ball is ±0.5mm;

Physical properties

After soaking in 40 ± 1 ° C water for 48 hours , the wet density changes from 0.90 to 1.20 g/cm 3 . and the diameter change rate does not exceed 10% of the sponge rubber ball diameter.
In addition, after soaking in water for a period of time, individual rubber balls may swell too much, causing the diameter to exceed the standard,these balls should be replaced in case the tube is blocked

Our product have passed ISO9001 & IATF16949 , FDA ,REACH ,ROHS ,UL certificate
