About the material
What makes natural rubber worth growing
Before it is a grade on a specification sheet, natural rubber is a living crop — tapped, collected and processed by hand long before it ever reaches a factory line.
Latex from a living tree, engineered into a dependable raw material
Every grade in our range begins as latex tapped from Hevea trees across our Memot plantations. Careful clone selection, staggered planting and disciplined replanting keep each block productive for decades, while a controlled, quality-checked path from cup to factory keeps every grade consistent, batch after batch.
- Elastic and resilient under repeated stress
- Naturally resistant to impact and abrasion
- Dampens vibration and noise better than most synthetics
- A renewable, carbon-sequestering crop
How it’s made
From tree to bale
Every grade passes through the same five stages before it reaches a customer’s line — the process that turns raw latex into a specification manufacturers can build on.
Step 01
Tapping
Before sunrise, when latex flow is at its strongest, tappers open a fine, shallow incision in the bark — angled to guide latex into a collection cup without harming the tree’s future yield.
Step 02
Collection & coagulation
Cups are gathered daily. Latex destined for concentrate is stabilised and cooled immediately; the remainder is left to coagulate naturally into field cup lumps ready for the factory.
Step 03
Washing & processing
At our own processing lines, raw material is washed, granulated and blended to even out quality, then dried under controlled conditions before it is pressed or drummed.
Step 04
Grading & quality control
Every batch is lab-tested against recognised international parameters — plasticity, dirt content, ash and volatile matter — before it earns its grade.
Step 05
Baling & export
Approved rubber is pressed into standard bales or drummed as latex concentrate, then packed and shipped with full batch traceability to ports worldwide.
Grade families
Four families, one standard of consistency
Each family serves a different processing need — but all are produced under the same traceable, quality-controlled supply chain, from plantation to port.
Technically Specified Rubber (TSR / CSR)
Block rubber graded to measured technical parameters rather than appearance — the workhorse grade for consistent, high-volume compounding.
Centrifuged Latex Concentrate
Liquid natural rubber concentrated to 60% dry rubber content, ammonia-preserved for dipped goods, gloves, adhesives and foam.
Constant-Viscosity & specialty
Viscosity-stabilised (CV) and low-viscosity grades engineered for demanding, high-precision applications where processing behaviour must not drift.
