Latex caps are very inexpensive. They do not last very long. They can pull on hair or be uncomfortable. Silicone caps are more expensive but last longer and may be more comfortable. Both latex and silicone caps will keep the hair relatively dry. They may help keep goggle straps from slipping. Lycra caps are the most comfortable and do not pull hair. They come in many colors and patterns. Lycra caps are not waterproof and only serve to keep longer hair from swishing around.

Lycra (Spandex) is softer and has greater stretch capability allowing for more flexibility. Its fabric has a rubberized elastic material. This is especially important for Synchro Swimmers. However due to the rubberized elastic material Lycra tends to breakdown earlier than Polyester because the chlorine attacks the rubberized elastic material in the fabric.

Latex is a milky white liquid composed of rubber particles dispersed in water. This material is whipped with air to form a foam, which is cured to make our mattresses.

Saline implants are filled with a “Normal Saline” solution which is basically sterilized water with added sodium chloride (salt). Should the implant rupture or leak, this saline solution, just like water, would be absorbed completely by your body. Silicone implants are filled with a silicone gel and are currently utilized only under guidelines set by the FDA as part of a long term study of their safety.

One style incorporates the stretch fitted design and the other cap uses a standard velcro closure for people who like the adjustability.

The natural latex core in the Royal-Pedic 7-Zone Natural Latex Mattress conforms to the body and provides the right level of support in all the right places. In addition, it is naturally antibacterial and resistant to dust mites. Royal-Pedic Cotton Mattresses feature the Royal-Flex innerspring system, which has 85% more coils than standard mattresses and also provides excellent orthopedic support. See the Royal-Pedic Mattress Buying Guide to learn more.

The most common material used to make condoms is latex, a type of rubber with very small pores that keep sperm and the smaller HIV virus from passing through. Latex is strong but susceptible to breaking when exposed to high friction and excessive pressure. To mitigate these problems, a water- or silicone-based lubricant should be used both on the inside and outside of the condom.

A lower price without sacrificing quality. Natures Rest is a manufacturer of finished latex mattresses,just as we are. They purchase premium Talalay latex from Latex International the largest supplier of latex in the United States. We too purchase only Talalay latex for our mattresses. The difference is Nature's Rest is sold to sleep shops and mattress stores which in turn sell to the public.

Tempurpedic is made from visco-elastic foam and is a relatively new type of foam in mattress manufacturing. It is temperature sensitive and in cold environments can feel very firm as it molds to your body. And when you move or change positions it is slow to mold to your body. Originally it was offered in only one firmness by Tempurpedic, a little over 6 pound density but now is offering a less firm density in the 5 lb area. unlike latex which offers a wide range of firmnesses.

Latex is natural and memory foam is synthetic; memory foam is temperature sensitive, while latex foam is not; lastly memory foam is denser (heavier) than latex foam.

Tempurpedic is made from visco-elastic foam and is a relatively new type of foam. It is temperature sensitive and in cold environments can feel very firm as it molds to your body. And when you move or change positions it is slow to mold to your body. In general terms it is sold by the major foam manufacturers in 3 pound, 4 pound and 5 pound densities. Tempurpedic visco foam has until recently been in the upper 5 pound area.

Overall silicone implants are softer and feel more natural than saline implants. In addition, silicone implants are much more expensive than their saline counterparts.

Silicone is a synthetic polymer, derived from silicon metal. The nature of its origin gives it a number of significant advantages over conventional rubber polymers. Silicone is available in the form of rubbers, greases, and fluids. No. Silicone is not affected by extremes of weather ? hot, cold, dry, wet, or humid. It also has excellent resistance to UV and ozone degradation.

Due to environmental and health and safety concerns however, this practice is seldom carried out today.

Latex Gloves are made of natural rubber latex. They provide superior barrier protection and are considered best for fit and function. Also, they are very durable. Nitrile Gloves (Latex Free) are an oil-based product which has similar physical characteristics of latex gloves. They stretch like rubber, although they have no latex in them. They are normally blue or green in color and offer good barrier protection.

The Talalay process is a highly controlled, sophisticated latex manufacturing process that produces the highest quality and most consistent latex available in the world. The Dunlop process is the most commonly used production method globally. It creates a firmer product that is used more as base core component. The major difference between the two processes is what happens in the mold just prior to the initial latex curing stage.

Natural latex is made from 100% natural rubber. Talalay latex is a type of latex that combines natural and synthetic latex usually 70% natural latex and 30% synthetic rubber made from raw materials derived from oil based products.

Natural latex is obtained as the sap which is exuded when the bark of the tree, Hevea Brasiliensis, is cut or "tapped". The rubber phase is ca 93% natural hydrocarbon; the remainder comprises natural products such as mineral salts and proteins. Rubber tress are cultivated, mainly in South East Asia, through a new planting and replanting program by large scale plantation and small farmers to ensure a continuous sustainable supply of natural latex. Synthetic lattex is derived from petrochemicals.
