Development of the Rubber Industry

The rubber industry

At first most of Indonesia's natural rubber is traded in the form of rubber sheet rubber smoke crunches (RSS = ribbed smoked sheet), but since the technology was introduced rubber crumb (crumb rubber) in 1968, rubber production in sit down, switch to rubber crumb, not less than 90% of national production of natural rubber is rubber crumb every year.
 

Demands a high demand from the transportation sector to natural rubber filled with hard rubber sheet, rubber because this type requires a long processing time that is 7-14 days. With crumb rubber technology, rubber materials quickly though, less than 1 day can be processed into the raw rubber is ready for sale. In addition, the quality of the rubber crumb assessed based on the results of physico-chemical analysis, so it is considered more "fair" than the quality of the rubber sheet were assessed only on the basis of visual observation and is subjective.




High market demand for crumb rubber to be used as materials for engineering components especially motor vehicle tires, and supported by guarantees availability of raw materials (if rubber material), led to the development of crumb rubber technology today is so rapid. In 1969 there were 65 factories, is now about 115 active crumb rubber factories operating in Indonesia.
 

Lateks rubber

 At the time of the rubber sheet natural rubber production still dominates, farmers play a role as a producer of latex, and many are used as well as rubber processing to sit. However, since the application of crumb rubber technology, farmers generally only acts as a provider if a lump materials and slab. If the lump is a material made ​​from rubber latex is coagulated into a bowl shaped around 10-15 cm in diameter, while the thin slab-shaped beam to measuring approximately 35cmx50cm, 20 cm thick.

If rubber material from farmers sold to final processors that crumb rubber plant to be processed into crumb rubber types SIR (Standard Indonesian Rubber) 10, or SIR 20. Treatment involves a series of processes ranging from size reduction, washing, homogenization, drying and packaging.

Rubber Roller (Rubber Roll) is one of many components applied in a variety of industries around the world. Made of rubber with NBR material, non-NBR, Urethane, etc.. As cylindrical iron in the middle. This component is usually used as one component of drive on Conveyor Belt Unit, Printing Machine, Transporting Unit in the Canning Industry and Food - Beverages, etc..

Silicon rubber for PU/poly resin products, unsaturated resin products, plaster products, candles and gypsums crafts, toys, soap molds, statues,casting molds making, etc.

TinSil tin silicone mold rubbers silicone mold rubbersare two-part, room temperature (RTV) curing systems that are used primarily for casting resins such as polyester, polyurethane, epoxy as well as polyurethane foams and low melting metals. This includes casting cold cast bronze art objects where the resin binder is EasyFlo 60 or EasyFlo clear

TinSil rubbers are pourable as supplied or can be thickened with Tin thix liquid thickener for brush-on mold applications. A brushable/sprayable version called TinSil brush is available for
use by hand or with low cost, portable equipment.

TinSil systems do not require mold release and offer excellent chemical resistance and long mold life during casting. TinSil molds do have a limited shelf-life when cured (library life) so they are not recommended for extended storage. TinSil 80-Series molds are designed for longer library life compared to TinSil 70-Series and other available tin silicone systems.



 Here's a little overview of the rubber molding for craft

(7) Sample are available for free charged
(8) MOQ: 200KG

3.FOQ of RTV-2 mold making silicone rubber for toy cars :

Why does the RTV-2 silicone rubber for molding have few mold making times?
The silicone rubber mold has few molding times is due to follwoing reasons: adding too much silicone oil which will destroy the molecular of silicone rubber; making the mold for small and fine detailed products with higher hardness silicone rubber which is easy to break; making the mold for large products with soft silicone rubber which will reduce the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take the proper silicone rubber to make the mold for suitable products.

TIPS FOR USE ON CLAY

Since different clays have different features, there are clays which are sticky than the others and so affect the pop out effect, in the case, we would recommend:
- For polymer clay, bake your clay right in the mold without concerns of clay distortion from de-molding.
- Put the clay into the fridge for around 5-10 minutes.

FOOD GRADE
All our handmade flexible molds are made with silicone materials that comply with the regulations set forth by the Food and Drug Administration in FDA 21 CFR 177.2600. In addition, these materials have been subjected to extraction testing performed by an FDA approved and independent laboratory that specifically certifies their suitability for use with water based foods and also foods that contain fat.

NOTICE: If you make a mold for non-food purposes, DO NOT use the same mold with food.

CS2 Condensation cure Silicone rubber

We are pleased to announce that our Condensation Silicone Rubber now uses an improved formulation for better tear strength, improved durability and variable cure times through different catalyst ratios (see below and datasheet for new details on catalyst ratio).
Easy Composites' Condensation Cure Silicone Rubber is a low viscosity, two-part condensation cure silicone rubber. It is used for mould making where it is mixed (with its catalyst) and then poured around a pattern to create a flexible silicone mould.
Easy Composites' Condensation Cure Silicone Rubber has been specially selected for its ease of use, excellent performance and great value.
Once cured the silicone rubber is very soft and flexible making it perfect for casting complicated or intricate shapes where the cast part can be easily removed from the silicone mould. The long pot-life of our silicone allows plenty of time for careful pouring and self de-gassing although forced degassing in a vacuum chamber can also be performed if required.

Features

• Easy to use – no special equipment or conditions required
• High tear strength and excellent elongation (making removal of even complex shapes from the mould easy)
• Good chemical resistance to styrene and polyurethane
• Low viscosity – fantastic flow properties
• Great value!
