Different Types

The effect of different types and loading of cleaning agent on the tensile properties and swelling properties of natural rubber latex film were investigated. The aim for this study is to find the cleaning agent which is compatible with natural rubber latex with optimum loading. In this study, there are two different amine based cleaning agent used which are Monoethanolamine (MEA) and Di-(3-aminopropyl) ether of diethylene glycol (DG). Swelling test was done to support the tensile results. It is found that tensile properties of the sample with MEA cleaning agent is higher than control sample (without cleaning agent) and sample with DG cleaning agent. For the best cleaning agent compound, the different loading has been tested and results showed that optimum loading of cleaning agent are achieved at 5 phr. The effects of both types of cleaning agents and different loading of cleaning agents on tensile properties and swelling properties for cleaning mold application are discuss.

Npk Fertilizer

Natural rubber latex products filled with bleached banana skin powder were identified by burying samples in soil. Soil burial was carried out by adding NPK fertilizer and without fertilizer. One of the tests which was carried out was weight loss calculation. Weight loss calculation showed that natural rubber latex products filled with bleached banana skin powder biodegraded faster than natural rubber latex products without filler. The addition of fertilizer also contributed to biodegradability of samples. The other test was FTIR (Fourier Transform Infrared Spectroscopy) test. The results of FTIR test showed there were structure changes in natural rubber latex which indicated natural rubber latex had been biodegraded.

Rice Milling

Rice husk powder (RHP) is an abundant agricultural by product that is produced in bulk quantity as part of rice milling. This research is carried out to incorporate RHP with natural rubber latex (NRL) compound. Different loading of RHP is added to NRL compound and is foamed to make natural rubber latex foam (NRLF) using a well known technique called the Dunlop method. The tensile properties of modified NRLF is studied and compared with the controlled NRLF which has zero RHP loading. The morphology and micro structural characterization has been performed by Tabletop microscopy (TM1000). The tensile strength decreases at 2.5 pphr but increases again as the filler loading increases. Elongation at break decreases whereas modulus at 100% elongation (M 100) and hardness increases as the filler loading increases.
