Rubber Plant
| Add caption |
Rubber plants are easy to grow and care for, and make lovely
additions to any home or office. This plant does well in a variety of
conditions, and is more likely to outgrow its home than die there.
Rubber plants prefer warm temperatures. Although rubber plants
adapt quickly to household and office temperatures, for best results,
maintain a day-time temperature of 80 degrees Fahrenheit or more, and a
night-time temperature of 65 degrees.
Rubber plants require adequate soil moisture, but over-soaking
the soil will cause problems. To avoid over-soaking, use pots that
drain. If the pot is set in a saucer, discard the excess water after
each watering.
With proper care, rubber-plant leaves will retain a glossy
appearance. Gently wipe leaves with a moist tissue or soft cloth to
remove dust. To remove stubborn stains, add a small amount of hand soap
to the water. To give leaves a shiny appearance, wipe them with a cloth
moistened with leaf-shine products available at your favorite garden
center or nursery.

Rubber Treatment
Rubber articles e.g. rubber latex gloves have an adherent anti-tack coating comprising a mixture of a) a carboxylated synthetic rubber latex having a minimum film forming temperature (MFFT) of 10° C. or above, with b) a latex polymer having an MFFT below 10° C. and/or c) a water-soluble organic polymeric hydroxy material. Component b) tends to confer non-slip properties while component c) tends to confer lubricating properties.1. An article of rubber having a surface provided with an adherent anti-tack coating which coating comprises a mixture of: a carboxylated synthetic rubber latex polymer having a film forming temperature (MFFT) of 10° C. or above; with a partly or wholly water-soluble organic polymeric hydroxy material; the weight ratio of the said carboxylated synthetic rubber latex polymer to the said partly or wholly water-soluble organic polymeric hydroxy material in the anti-tack coating being from 0.25:1 to 20:1.
Rubber articles
The rubber industry provides the most important market for precipitated silica which plays the role of white reinforcing filler in tires, rubber footwear and mechanical rubber goods.
Precipitated silica provides excellent reinforcing properties such as hardness, tensile tear and abrasion resistance. Its high purity makes possible the manufacture of translucent and colored articles.
It has fast incorporation and good processing properties at low viscosity values reproducing excellent rheometric and mechanical properties depending on the formulation where is used.
