In house dispersion manufacturing cost

The Real Costs of manufacturing In-House dispersions

By | Blog

When comparing the raw material costs of in-house production with the purchase of ready-made water-based dispersions, one might initially assume that manufacturing in-house is cheaper. However, a true cost comparison must account for various additional factors involved in in-house dispersion production.

CaO in EPDM Rubber Profiles

Alleviating the downside of using CaO in EPDM Rubber Profiles

By | Blog

The permissible standard for Calcium Oxide is 5 milligrams of CaO per cubic meter of air averaged over an eight-hour work shift. Some countries have recommended 2 milligrams per cubic meter. CaO has been linked to many health hazards like irritation of the eyes, nose, throat and skin. Severe burns may result from contact with this chemical. It may also cause bronchitis and pneumonia. Long term exposure is said to cause skin ulceration and perforation of the nasal septum.

Accelerators to Control Blooming in EPDM (Part 2)

By | Blog

Ethylene-α-olefin elastomers, particularly ethylene-propylene-diene (EPDM) rubbers, are excellent all-purpose rubbers. Environmental factors such as oxygen, heat UV and ozone tend to degrade the rubbers.  These factors cause free radicals to form which attach to the polymer chain and make the rubber harder.

Accelerators to Control Blooming in EPDM

By | Blog

Curing in EPDM (Ethylene propylene diene) rubbers is much slower compared to curing in conventional diene rubbers. Therefore, it usually requires a high concentration of highly active curing accelerators. This, though, has its own issues as there is a limit to using high amounts of accelerators, as their activity tends to level off with increased concentration and BLOOMING problems start.

Static electricity has its uses, no doubt. Think laser printers, photocopiers and flash bulbs for photography. Why do we call this static electricity? Static electricity is a kind of electric charge that stays in one place, as in it is really is static. On the other hand, current electricity or electric current), is electricity that moves from one place to another along a definite path called a circuit.
