By Chris Wagner, Marketing Manager
In an our continual efforts to help our customers understand changing market conditions, we are posting this entry as it concerns notices we are receiving about the rising costs of zinc in the marketplace over past several months.
Enclosed is a chart showing how the price of zinc has increased over the past two years on the London Metal Exchange (LME). Zinc’s outlook has been boosted due to heavy demand in industrial applications, and because of several mine closures slated for both this year and next. In addition, LME-monitored warehouse inventories have decreased 20% since early spring, 2014. This is important because it will increase ChemSpec’s pricing on our zinc-based products, beginning this month and potentially for the considerable future. The following product prices will likely be impacted due to these rising costs:
|Zinc Borate 2335|
|Zinc Oxide CR-4|
|Zinc Oxide HT-10|
|Zinc Oxide HT-2C|
|Zinc Oxide HTA|
|Zinc Oxide HTR|
|ZnO Grade 400|
|ZnO Grade 500|
|ZnO Grade 800|
|ZnO Grade 800H|
|ZnO Grade 800HSA|
|ZnO Grade 800L|
And although we have not yet seen rising prices related to all of these products, we anticipate in the near future to receive price increases, and in turn, we will be forced to pass these costs along to our customers.
Additionally, many of you who use standard grade ZnO, which is an equivalent to our new supplier ZINC OXIDE LLC’s products, have voiced that your ZnO prices have remained relatively steady over the last 12-24 months. ChemSpec advises you to now begin continually checking on pricing from your other ZnO suppliers, as many of these suppliers have likely been selling-off inventory over the last several months that do not reflect the above price shifts. But once these suppliers begin to bring-in fresh zinc-based product, they will be forced to increase their sale price(s).
ChemSpec will continue to track rising zinc prices, and will make every effort to inform you as soon as possible on product price changes. I ask that you not hesitate to contact us with any concerns you may have with these potential price increases, and please feel free to continually monitor zinc pricing changes with ChemSpec moving forward.

ChemSpec is pleased to announce that Sales Coordinator and General Counsel, Chris Wagner, has been appointed to the Board of Directors for the Association of Rubber Products Manufacturers (“ARPM”).
Chris acts as ChemSpec’s sales coordinator and marketing director, and also as an actively licensed attorney, he is the company’s legal adviser. Chris also supports the company, its suppliers and customers, on various regulatory matters.
ARPM was established in October of 2010 after elastomer products company executives belonging to the RMA mutually agreed that a stand-alone association was needed.
Created for the purpose of aiding rubber products manufacturing executives in leading more successful enterprises, ARPM’s core mission has been designed to provide waste reduction, benchmarking, networking, international management of product standards, and educational opportunities to its member executives. As the only national association for rubber products companies, ARPM members range in size from small manufacturing producers to multi-billion dollar conglomerates.
For more information on ARPM’s benefits or joining the organization, feel free to reach-out to Chris, or visit ARPM’s website: http://www.arpminc.com.
ChemSpec Ltd. is pleased to announce its entry into an exclusive distribution agreement with Zinc Oxide, LLC(“ZNO”)—North America’s newest zinc oxide manufacturer. ZNO, using the French Press method, produces high-quality zinc oxide materials from high grade and special high grade zinc metal, as well as from recycled zinc.
ChemSpec will distribute ZNO’s products regionally into the Illinois, Indiana, Kentucky, Michigan, Ohio, and Pennsylvania rubber compounding markets. ChemSpec will concentrate primarily on accounts purchasing less-than-truckload (“LTL”) volumes. ChemSpec does currently distribute an active grade zinc oxide material (Zinc Oxide HT-Active), and feels that this active product will nicely complement ZNO’s zinc oxide line.
ChemSpec is an Ohio-based specialty chemical and polymer distributor, who sells product primarily into the rubber, adhesive / sealant, plastic, and ink markets. ChemSpec’s product line entails synthetic polymers, such as polyisoprene and various molecular weights of polyisobutylene; and polymer additives, such as silane coupling agents, various waxes, calcium products, magnesium products, blowing agents, process aids, accelerators, plasticizers, adhesive tackifiers, dithiocarbamates, antioxidants, and insoluble sulfur.
For more information, please contact Chris Wagner (email: firstname.lastname@example.org, Mobile: (330) 958-4316) or your respective ChemSpec sales representative. Or you may visit us at http://www.ChemSpecLtd.com.
ChemSpec has introduced a next generation physical peptizer/ process aid from Performance Additives, Sdn. This revolutionary product is named Ultraflow 440. UF 440 is a reaction blend of mixed metal soaps. UF 440 Performs well in both natural and synthetic elastomers.
UF 440 performs well to improve filler dispersion; particularly well with “white” fillers. The UF 440 overcomes “filler reticulation” to keep silica from forming secondary agglomeration during the mixing process.
UF 440 performs well in both sulfur and peroxide vulcanization, while maintaining good scorch safety and better reversion resistance.
After the final mixing process, UF 440 is designed to stabilize compound viscosity—even after several days—allowing for lower viscosity until the final production process.
UF 440 also improved rubber molding and extrusion characteristics.
Further, Ultraflow 440 is sanctioned by the FDA pursuant to 21 CFR §177.2600.
For more detailed information, please contact myself or your respective sales representative.
We’ve noticed, since we began distributing OCCL’s insoluble sulfur products, that some customers are using Chinese manufactured material, due to its cheap price. We strongly believe that you should consider ChemSpec’s insoluble sulfur (DS OT 20 HD & DS OT 20 HS)–even if priced higher than the competition–because of our products’ quality. This really comes down to the old adage: you get what you pay for!
Generally speaking, to be used properly in commercial manufacturing, insoluble sulfur needs to have the following characteristics:
- High Thermal Stability,
- High Insoluble Sulfur Content,
- Controlled fineness,
- Absence of any hard particles,
- Low ash Content, and
- Absence of any foreign particles and low Iron Content.
The above is necessary to ensure that the material does not bloom , disperses well, and there is no ingress of undesired material inside the rubber compound.
You will notice with Chinese-manufactured Insoluble Sulfur–from any supplier–that several of these parameters are likely lacking. This is the reason that no Chinese suppliers presently have Global approvals from any of the major tire manufacturers (NOTE: our product does have global approvals from the international tire producers). The processes used by Chinese producers commonly have some very basic, but serious, production issues–namely the following:
1. Production technology that cannot attain the above-described desired production parameters;
2. Production technology that cannot assure stability in the production performance parameters;
3. Their production processes do not use high grade quality stainless steel, which causes high corrosion levels and increased iron content;
4. Inadequate grinding technology, which does not allow uniform grinding; causing particle size distribution problems; and
5. Manual handling during some important production steps, translating into improper ingress of foreign material (our supplier’s process is automated).
Oftentimes, these failures result in, over time, the Chinese material chemically changing back to straight sulfur. So this problem is amplified if a customer is purchasing this material and having it shipped from China to another continent (i.e. North America), where the product sits for several months before being placed into a recipe.
