To minimize the loss of quality, we recommend a maximum storage temperature (TS max.) for each organic peroxide product. For DMDBH TS max.= 30 ípC When stored under the recommended storage conditions, DMDBH will remain within the specifications for peroxide of at least 6 months after delivery. Thermal stability Organic peroxide are thermally unstable substances, which may undergo self-accelerating decomposition. The lowest temperature at which self-accelerating decomposition of a substance in the original packaging may occur is the Self-Accelerating Decomposition Temperature (SADT). The SADT is determined on the basis of the Heat Accumulation Storage Test. Organic peroxide are thermally unstable substances, which may undergo self-accelerating decomposition. The lowest temperature at which self-accelerating decomposition of a substance in the original packaging may occur is the Self-Accelerating Decomposition Temperature (SADT). The SADT is determined on the basis of the Heat Acumulation Storage Test. For DMDBH SADT: 80ípC Packing and For DMDBH, the standard packaging is 18kg/drum. Transport Safety and handling: Keep containers tightly closed. Store and handle DMDBH in a dry well-ventilated place away from sources of heat or ignition and direct sunlight. Never weigh out in the storage room. Void contact with reducing agent (e.g.amines), acids, alkalines and heavy mental compounds (e.g. accelerators, driers and metal soaps.) Applications DMDBH is used for the crosslinking of silicone rubber. Rubber compounds contain DMDBH have excellent scorch safety.

Properties: It is yellow to brown schistose or granular solid, synthesized by formaldehyde, modifying agent, active agent and parasubstituted alkylphenols which have different number of carbon atom in the alkyl groups. Applications:The super tackifying resin has the characteristics of long-term effective, nice moisture stability and high viscosity-promoting ability. It's viscosity-promoting ability is similar to para-tertbutylphenolaceylene resin and superior to para-tert-butylphenol(or para-tert-octylphenol) formaldehyde resin. This product should be added under the temperature higher than it's softening point in the early period of mixing, to ensure the resinf+s homodisperse and to get the best viscosity-promoting effectiveness. It can save the use level of processing oil to a certain degree. The recommended dosage is 2-5 phr. Storage: Kept in dry and ventilating place, protected from heat and fire, the storage life is 18 months. The products that exceed storage life and qualified can be used. Package: Packed in knitted bags lined with a layer of kcraft paper bag and a layer of plastic bag. The netweight is 25kg per bag.
Used as a conventional compound chemical peptizer, non-toxic and harmless to human body for no containing of penta chloro thio phenol, It may effectively promote the molecular chain breakage of rubber during mastication and prevent free radicals from recombination to large molecules, which can effectually improve the effect of crude rubber plastication and stability of plasticity, and enable good dispersibility for other compounding ingredients to ensure the homogeneity of different parts during plastication for the same batch of compound mixed material as well. 25kg/bag(paper-plastic compound bag).

PU binder for synthetic running track and EPDM field base layer installation . PU binder for safety playground and wetpour . PU binder for rubber mat production . PU binder is an un pigmented and solvent free single component Polyurethane Binder of medium viscosity. It is based on MDI with 100% solid content and high standard quality control of polyether raw material and additives material for binder's intensity, life time, smell ,color and UV resistance characteristics. The defined viscosity of PU binder effects an excellent mixing with rubber granules while where is hardly any run off from the granules. Another characteristic is the suitable curing time and therefore application time allowing day construction joints to be easily and correctly done . The yellowing that occurs when PU binder is exposed to UV-light does not affect its mechanical properties.PU binder is moisture curing .
