  Table 1.1 - Production and Consumsion Comparison of Natural Rubber and Synthetic Rubber

  Average number of synthetic rubber entrepreneur, realise that total use of natural rubber cannot increase without decreasing the total number of request of synthetic rubber. The world industries still need both types of rubber. These two types of rubbers have their own marketing share. They are not actually killing or fighting each other fully, but they have complementary nature towards each other.

  Types of Natural Rubber

  There are various types of natural rubber. The most common or well-known is the processed rubber. Processed rubber have some done and some half-done. Types of natural rubbers are:

  Processed rubber material ( Plantation latex, Thin Slab, Wind Sheet, Fresh Lump)

  Conventional Rubber ( Ribbed Smoked Sheet, White crepe and Pale crepe, estate brown crepe, compo crepe, thin brown crepe re-mills, thick blanket crepe ambers, flat bark crepe, pure smoke blanket crepe, and off crepe)

  Concentrated Latex

  Block Rubber

  Crumb rubber

  Tyre rubber

  Reclaimed rubber

  Processed Rubber Material

  This rubber is a plantation rubber as it is made out of a lump of plantation latex recovered by a tree called Hevea Brasiliensis. There are 4 types of processed tuber material:

  Plantation Latex

  Wind Sheet

  Thin Slab

  Fresh Lump

  I.Plantation Latex

  Plantation latex is liquid latex that can be gained from tapping the rubber tree. This liquid will group together with or without stabilizer (anti-coagulant agent). Plantation latex also has requirements to reach the marketing standard.

  The requirements are:

  It needs to be filtered using 40 mesh strainer/filter.

  No leaf, branches or other dirt.

  It is not mixed with latex slurry, water or latex’s serum.

  It is white in colour and smells like fresh rubber.

  Class 1 plantation latex contains 28% dry rubber content and Class 2 plantation latex contains 20% dry rubber contain.

  II.Wind Sheet

  This is the filtered and blobbed with formic acid processed rubber material. It has already been milled but just not done yet. There are also requirements for wind sheet to reach the marketing standard.

  These requirements are:

  Latex need to be milled and blobbed to release water or its serum.

  Mill development is used as the last milling.

  Dirt cannot be visible.

  While storing, it cannot be exposed to direct sunlight and water.

  III.Thin Slab

  It is a processed rubber material that is blobbed using formic acid. There are also requirements to reach the marketing standard.

  Not mixed with not fresh blub.

  Water or serum has to be released by milling or compression.

  Dirt is not visible.

  While storing, it cannot be exposed to direct sunlight or water.

  Thin slab class 1 has 70% dry rubber content and thin slab class 2 has 60% dry rubber content.

  First level of thickness is 30mm and second level of thickness is 40mm.

  IV.Fresh lump

  Processed rubber material that is not made out of plantation latex happens naturally inside a bowl. Fresh lump also have requirements to meet the marketing standard.

  These requirements are:

  Dirt cannot be visible.

  While storing, it cannot be exposed to direct sunlight or water.

  Fresh lump class 1 has 60% of dry rubber content and fresh lump class 2 has 50% of dry rubber content.

  First level of thickness is 40mm and second level of thickness is 60mm.

  Conventional Natural Rubber

  There are types of processes rubber that falls under conventional natural rubber. These processed rubbers are what you call “crepe” and “sheet”. In the Green Book published by the International Rubber Quality and Packing Conference, this type of natural rubber falls under the quality section.

  Types of Conventional Rubbers are:
