PSH is a specially treated high ammonia centrifuged natural rubber latex which possesses similar properties as a single centrifuged latex except for some outstanding advantages. The outstanding features of this grade are its low microcoagulum level(measured by 300 mesh sieve) and good filtrability compared to the normal single centrifuged latex. Properties of good filtrability and low microcoagulum are of utmost importance to some natural rubber latex industries, particularly the latex thread, adhesives and condom industries. These advantages are also applicable to other NR latex dipped products such as catheters, baby teats/soothers, medical gloves/tubings and toy balloons
