Environment Protection --- Low Zinc Activator Topfine® CR510

Low Zinc Activator Topfine® CR510

BACKGROUND
European Commission has confirmed the EU-wide ban on the use of zinc oxide at medicinal levels in piglet feed in 2017, EU 2017/1413 Regulation made further limit on zinc oxide in cosmetics, in 2016, California Senate Bill 1260 even tried to ban the sale of motor vehicle tires in California that contained more than a certain amount of zinc by weight. To follow this tread, we have developed Low-Zinc Activator Topfine® CR510, it has the characteristics of low zinc content, high vulcanization activity and excellent dispersion. Zinc content is only half of common Zinc Oxide (ZnO), which is environmentally friendly, and meets the requirements of rubber products performance.

Activator Topfine® CR510 is prepared by means of liquid phase reaction, which is obtained by reaction under specific temperature and PH conditions, also obtained under dehydration process and granulation technology.

PRODUCT HIGHLIGHTS
● High activation efficiency
● Nanometer grade dispersion, no agglomeration
● Good dispersity of processing, no dust
● Excellent physical properties (comparing with equivalent ZnO indirect Process), can replace ZnO-80 Masterbatch equivalently)
● Environmentally friendly, Zinc content 40%
● Effectively increase the scorching time, improve the processing safety, the vulcanization speed faster than that of the common zinc oxide.
● Low content of heavy metal, passed SGS test, meet RoHS standard

SUGGESTED APPLICATIONS
CR510, as an upgraded product of common zinc oxide, can be used as an efficient activator for NR (natural rubber) and SR (synthetic rubber).
In rubber products such as tires, it can be used in the same amount instead of zinc oxide.
It has good activation effect the Sulfonamide type, thiazoles type, and thiuram type accelerator.
It is recommended to use with magnesium oxide together to improve the scorch resistance of the compound when it is used as vulcanizing agent for CR.
It has better activation effect in the effective, semi-effective and peroxide vulcanization system.

New Material -- Multi functional rubber agent Topfill® N90 / N98

As a new Multi functional rubber agent, Topfill ® N90 / N98 can be used as rubber anti-fatigue agent, rubber char forming flame retardant, rubber reinforcing agent, rubber filler. Its main component is modified Silica. Topfill ® N90 can replace Sillitin N85 in automotive hose, sealing strip, tyre and other rubber producing, no affect on the performance in the formulations. More importantly, the cost is much lower than Sillitin N85.  Topfill ® N98 shows amazing anti fatigue property in tyre, conveyor belt, V-belt, bumper application. The particle size distribution is 60nm~500nm, the aggregate structure is a single sphere, with irregular groove surface and relatively lower structure. ANALYSIS OF TEM The smallest structural unit is spherical. With extremely low surface activity, structural units could not be agglomerated. The smallest structural unit has uneven surface, with certain reinforcing performance. Nano grade structural unit has a very low degree of structur...

TOPLINK@ 439, substitute for Sartomer SR634, same performance, different cost.

Zinc dimethacrylate is an unsaturated hydroxy acid salt that polymerizes in peroxides and cadmium-magnesium vulcanization systems and is partially grafted onto rubber molecular chains to produce a large number of salt-bonded cross-links, thereby greatly improving the degree of cross-linking of vulcanizates. Modified Zinc Dimethacrylate improves its dispersion in the rubber compound and reduces the risk of scorch.   Toplink® 439 is Modified Zinc Dimethacrylate , a difunctional solid dimethacrylate for general applications requiring enhanced adhesion and scorch retarding. Toplink® 439 is recommended for use in peroxide cured systems for coatings and formulations requiring enhanced adhesion. ADVANTAGE:  1. Contains non-nitroso inhibitor package for scorch resistance  2. High crosslink density  3. Fast cure response  4. Improves metal adhesion  5. increasing hot tear strength  6. Better elongation, high tear strength, higher tensile strength...
