|
|
Character:white or light yellow crystal(or powder),no poison ,dissolve in benzene ,ethanol and acetone etc. It does't dissolve in water.
|
The use of the product:It's the material links the natural rubber with all kinds of synthetic rubber, It's used to many dynamic products ,heat-resisting products,meridan tire .engineering tire,and fluid sealant etc.
|
Introduction:DTDM is the offering body of the ,sulphur.It will release a percentage of 27 active sulphur in the temperature of vulcanization ,it will produce a high connecting effect to the rubber.
We blend DTDM in the rubber,part of whole replace the sulphur, so make the active sulphur gain an ideal physical machine function .That makes up half effective vulcanizattion rubber resist not only fatigue but also oxdation.
According to DTDM's special chemical strcture in the vulcanization temperature,in addition to release active sulohur, so that make the rubber produce a high connecting function , at the same time ,it resolve morphlinyl, which has the second amine structure feature .This kind of free radical can not only resist heat and oxygen ,but also delay coking time ,so that speed up vulcanization .So,DTDM has a performance of vulcanized agent,promoter, anti oxidant and prevent coking comprehensive effect .So many rubber product enterprise including domestic and overseas pay attention to DTDM.
|
| Product advantage: |
| 1:DTDM can fit 140℃~200℃ vulcanization temperature .the coking safety is good ,the vulcanization speed is quickening when it reaches the vulcanization temperature, it has an ideal vulcanization performance. |
| 2.DTDM doesn't spout frost in rubber. it doesn't polute , it's easy to disperse ,has a good processing performance. |
| 3.DTDM releases active sulphur ,it has a high vulcanization function ,it can improve vulcanized rubber's antireduction. |
| 4.DTDM can resolve morphlinyl which has amine ageingproof ,it makes vulcanized rubber have good resisting heat and antioxidation functions. |
| 5.DTDM has a fine heat-resistance ,if it is used to make dynamic resisting heat rubber product. it can reduce tocause heat producing Nr and SNR. It can reduce to cause heat producind Nr and SNR .it's an ideal rubber vnlcanized agent . |
6.the no dust oil extension DTDM which has been developed by us, except for above-mentioned advantage ,It has fine and moist function .It is not easy to fly into air in rubber processing ,It dosesn't pollute and it's easy to desperse.It's also easy to blend with rubber and other materials.
|
| Package and storage: |
DTDM product is packed in paper tub per 25kg .lined with PE plastic bag .the product should keep in vent and dry place ,The quality guarantee time is half a year.
