Homogenized Latex Centex HF
CENTEX HF is an ASTM Type 1 high ammonia, centrifuged natural rubber latex that has undergone additional processing after centrifugation. A low micro-coagulum content and filterability 3 - 6 times greater than regular centrifuged latex characterize CENTEX HF. High filterability latex has found use in a wide variety of dipped products including condoms and catheters.
