There are several distinct differences between silicone and latex rubbers, the primary difference being that latex is a natural product and silicone is man-made. Consumers may choose between silicone and latex versions of several plastic products, including pacifiers, caulking and rubber bands.Know More
Silicone is a clear synthetic product that has undergone testing to ensure its safety, and it is generally more durable than latex. Silicone products retain their shape better than those composed of latex. Latex is a natural, beige-colored, water-based material that is softer, more flexible and more eco-friendly than silicone. Over time, latex may begin to break down and show signs of wear due to its natural composition, while silicone does not age. Latex may also cause allergic reactions for some users. Allergic reactions usually occur within 30 minutes of contact with a latex-based product and cause itching and redness of the skin.
Silicone has a higher heat resistance than latex, which may be an important factor to consider when deciding between a latex and silicone sealant. Latex products may contain small, non-hazardous amounts of nitrosamines, which are known carcinogens. Latex materials are highly porous and tend to harbor more bacteria than silicone-based products. Neither silicone nor latex contains BPAs.Learn more in Chemistry
The difference between exergonic and exothermic reactions is that energy is released to the surroundings in an exergonic reaction. When an exothermic reaction occurs, the energy released to the surroundings is heat energy.Full Answer >
Sulfa is a type of pharmaceutical drug that contain sulfonamides. Sulfonamides are compounds that contain nitrogen, hydrogen, oxygen and the sulfur they take their name from. Sulfur is a chemical that is extremely small and unlikely to cause allergic reactions on its own, unlike sulfonamides.Full Answer >
Amylose is a glucose polymer with long chain-like molecules, while amylopectin consists of larger highly branched molecules (1 to 6). Glycogen consists of even more branches than amylopectin. Amylose and amylopectin are classified as starch, and are found in plants, while glycogen serves as the main energy reserve for animals.Full Answer >
Vermiculite is an alumino-silicate clay processed by heating to make it expand; it draws nutrients by soaking up water while perlite is volcanic rock, rich in silicon, which absorbs less water but aerates soil more efficiently. The two substances serve in different capacities in the potting of houseplants and flowers.Full Answer >
