Low tensile strength and poor tear resistance are the
other major drawbacks encountered in NRL products,
especially for medical gloves and condoms. Attempts have
been made to use carbon black [9], ultra-fine calcium carbonate
[10], modified montmorillonite [11], silica [12] and
starch [1] to reinforce dry NR or NRL. However, these traditional
reinforcement materials are not so effective for
NRL. Therefore, it is essential to exploit new way to
enhance the ageing resistance and mechanical properties
for NRL products.
