Ⅰ、Good Antioxidant Properties

DTBHQ'superiority in preventing high temperature oxidation、light stabilization and does not turn colors in sunshine. Easily dispersed in the polymer , does not affect curing effects.

In the plastic products, it has the same efficiency with 1010、4010NA in the area of antioxidant、anti-aging, it is even better then the last in some area. It has a good anti-aging in adhesive.using different way to take the exam, taking the three productions Antioxidant DTBHQ 、Antioxidant 4010N and Antioxidant 1010, as a result, Antioxidant DTBHQ is better.
In one word, Antioxidant DTBHQ is better than Antioxidant 4010N and Antioxidant 1010, in some area(especially in High-temperature), Use less but good result, cost less

Ⅱ、 safety
DTBHQ is a industrial antioxidant which odorless、tasteless 、nontoxic, it is safety than other antioxidant in using and does not pollute productions and environment. in the toxicity test, DTBHQ is non-carcinogenic effects to the big and small white rats in the dose of LD50=1500㎎/㎏,
Ⅲ、Stability
melting point:215～219℃，Boiling Point:313℃,The melting point is high than 4010NA'（80.5℃）、1010'（119～123℃）、264'（70℃)， It has excellent heat resistance and good compatibility,which does not affect the products’color, nature 、 processing, it is easy to dispersed,and has no impact in sulfide, also can increase the stability of plastics, rubber products.
Ⅴ、field
DTBHQ can play the role of Antioxidants, antioxidant, anti-poly agent, light stabilizers in the area of following productions:
Different Rubbers: Natural Rubber、Chloroprene rubber、NBR、CPDM 、BR、SBR and some light colored rubbers、 Latex products.
In the synthetic rubber. It is better using both DTBHQ and DNP.
Different synthetic resins and plastics: polyvinyl chloride（PVC）、Polyethylene（PE）、Polypropylene（PP）、Polystyrene（PS）、Polycarbonate（PC）、ABS、Polyamide hot melt adhesive and Cellulose resins
Various paints and varnishes, adhesives, lubricants, oil, photographic materials and medical supplies, and so on.
In short, DTBHQ is a additives about Organic polymers. , can be used as antioxidant, inhibitor, stabilizing ,and has different efficient . Commonly uses in the rubber, raw plastics materials and paint, grease category (including cosmetics), also can be used as the stabilizers of heat and light.
Ⅵ、 method of using
For the company which has used other industrial antioxidants or antioxidant, it is no need to change the production technology, formulations and methods.
replace original antioxidant by DTBHQ is ok. And it has the use method with antioxidant, antioxidant, inhibitor, light stabilizers.
The using area of DTBHQ is 0.1﹪--2﹪
