Remarks:
This report is for press cure data(170C*10M ). For the rapid inspection of shipments, the strength of FKM will increase significantly after postcure.Please contact us for the data report of the post cure.The condition of post cure is: 235 ° C * 24H.
Process safety instructions:
(1) Warning of mixing:FKM could not be mixed with metal powder or Amines;if mixing with Sulphur over 1% will hinder the vulcanization of FKM, it will cause the rubber to be completely unable to use.
(2) Warning of vulcanization:When FKM is vulcanizing at high temperature, it will produce trace HF toxic gas, ventilation is suggested during production.
(3) The test data is measured through professional inspectors,and as the technical specifications of our products. This can not be represented the test of products of different production processes by customers.
(4) The storage temperature is controlled at indoor temperature and below, and the humidity is not more than 75%. It should be protected from light and ultraviolet rays. At the same time, we must do a good job of dust and pollution prevention when using rubber.Pay attention to the first in and first out, the rubber must be used up within the warranty period.
