FILL FACTOR

In the rubber mixing process, especially for internal mixers like a 110-liter volume mixer, the recommended fill ratio typically falls within the range of: Fill Ratio: 65% to 85%The fill factor or fill ratio is typically calculated as: Fill Ratio (%) = (Batch Weight / Mixer Chamber Volume) × (Specific Gravity of Compound) × 100 Example: Mixer Volume = 110 liters Target Fill Ratio = 75% Specific Gravity of Rubber Compound = ~1.2 So: Batch Weight = (110 × 0.75) / 1.2 ≈ 68.75 kg This means around 68–72 kg would be an optimal batch weight for a typical compound with SG ~1.2 in a 110 L mixer.

ReTyre: Tyres Can Now Be Simply Zipped On. டயர்கள் இப்போது வெறுமனே ஜிப் செய்யப்படலாம

ReTyre: Tyres Can Now Be Simply Zipped On ReTyre claims that they have created the world's first modular tyre system. It is quite easy to change the suspension setting, tyre pressure considering the different riding conditions and even the riding kit but changing the tyre tread has not been an easy task like the rest. Basically, there is a base tyre, ReTyre and a slick road tyre that can be used on tarmac surfaces but it also has zips on the the sidewall, above the rim. The manufacturer claims that additional skins with different tread pattern covers the Retyre with the help of the zip on the sidewall. There are 4 different skins for different terrains such as the Winter Traveller, Trail Rider, Gravel Chaser, Ice Rider. The best part is that the skins can be fitted without removing the wheel and can be easily stored too. The question which comes into everybody's mind is whether the zippers can withstand the torture from riding on different terrains, and the answer to it is ...

J J Murphy: Kerala’s Rubber Man

J J Murphy: Kerala’s Rubber Man “On a rainy day in Ooty, South India’s famous hill station, some nuns were walking along a road in the cold. Suddenly, a car stopped by and the gentleman driving it offered them a lift. He asked why they were not using a vehicle in such inclement weather. The nuns replied that their convent did not have one. The next day, a local dealer delivered a brand new Dodge car to the convent. The astonished nuns thanked the donor. They also told him they could not keep the vehicle because there was no money to engage a driver or to buy petrol. The gentleman assigned a driver on his payroll to the convent. He also instructed a petrol bunk to forward the convent’s bills to his office.” This is an anecdote about a man you’ve probably never heard of – an Irishman named John Joseph Murphy (1872 – 1957). But in the rubber plantations of Kerala, Murphy is a legend. A planter who arrived in India at a very young age, it was Murphy who set up India’s first commercially su...

SHIN-ETSU DEVELOPS NEW TECHNOLOGY REDUCING THE AMOUNT OF PLATINUM USED IN SILICONE RELEASE COATINGS

SHIN-ETSU DEVELOPS NEW TECHNOLOGY REDUCING THE AMOUNT OF PLATINUM USED IN SILICONE RELEASE COATINGS Shin-Etsu Chemical Co., Ltd. has developed a Reduced-Platinum Reaction Curing System Technology, and is proceeding with productization by integrating this technology into silicone release coatings. Silicone release coatings generally use a platinum-based curing catalyst. However, platinum is an expensive precious metal, and due to such issues as the depleting of its limited resources, a reduction in the amount of usage in the curing process has been sought. By implementing a silicone composition that exhibits high reactivity, Shin-Etsu’s newly developed “Reduced-Platinum Reaction Curing System Technology” enables the carrying out of curing that results in the lowering of the amount of platinum usage by about 1/2 compared to that of conventional usage. Using this new technology, it is expect to contribute to resource saving, and at the same time, we will be able to meet the varied request...
