REF (Hevb1) and SRPP (Hevb3) are two major components of Hevea brasiliensis latex, well known for their allergenic properties. They are obviously taking part in the biosynthesis of natural rubber, but their exact function is still unclear. They could be involved in defense/stress mechanisms after tapping or directly acting on the isoprenoid biosynthetic pathway. The structure of these two prote...
This work focuses on the study the effect of ZnO nanoparticles on the vulcanizate properties of natural rubber (NR) latex films. Zinc oxide nanoparticles were synthesized by a simple and an efficient wet chemical method. The Powder X-ray Diffraction (PXRD) characterization confirmed the successful synthesis of pure ZnO and the average particle size was found to be 50 – 100 nm as indicated by pa...
ABSTRACT Specialty natural rubber (SpNR) latex, namely, deproteinized (DPNR) latex and epoxidized (ENR) has been produced to meet specific product's requirements. However, SpNR is normally used in the form of block manufacture dry products such as tires automotive parts. The applications into foam will be diversified. Findings indicate that foamability lower compared normal (LATZ) but shows lon...
Preparation and structure characterization of hydroxylethylmethacrylate grafted natural rubber latex
BACKGROUND Recent studies have shown that systemic or respiratory occupational responses to latex can be induced by inhalation of latex aeroallergens. OBJECTIVE Our objectives were to study the relationship between exposure to different latex aeroallergen levels and type I allergic reactions in subjects with occupational contact with latex and to assess a threshold value for latex airborne al...
