Rubbers Lab, Polymer Research Unit
National Metal and Materials Technology Center

2. 7 researchers and
11 assistant researchers

4. A unit that can provide, research and
development, technical and
knowledge and information support
as well as training of human
resource to the Thai rubber industry
and solve the problem of the lack of

5. Research Themes
1. Revolutionizing of
Raw Rubber Production Processes
- Constant-property rubber
- Less-pollution process

6. 2. Rubber Compounding for Specific
Property Improvement
- Improve product quality
- Develop new products

7. 3. Thermoplastic Natural Rubber
(TPNR)
The practice to add value to NR
and to recycle NR.

8. 4. Dynamic Properties Technology and Finite
Element Analysis Technology for Engineering
Rubber Products
These techniques can help to improve and develop the
quality of engineering rubber products.

9. Raw Rubber Projects
2003 ~
TAPS
ORL-RAT LD50:
Ammonia 12-44% = 350 mg/kg,
TAPS 95% = 1750 mg/kg

10. Ammonia VS TAPS
HA/LATZ TAPS Benefits
Obnoxious odor Odorless latex Personal healthcare
Carcinogen No carcinogen Product assurance
Highly toxic to cell Non-toxic to cell Manufactured risk
Base Neutral Environmentally friendly
High corrosion Low corrosion Maintenance costs

11. Sludge

13. Innovative Continuous Drying Process of
Natural Rubber by Twin-screw Extrusion
Technique
Continuous process with a
much shorter drying time
Cost reduction based on less
energy used
High quality dried NR products
in accordance with STR
Process and products offer
competitive advantage for Thai
NR industries
