At the design stage adding molecules/monomers with more rings than chains will make the polymer more rigid. If this option is not available, adding fiber or particles or fillers is the usual technique.
You can make a stiff polymer more flexible by adding plasticizers, but going the other way is more difficult. Technically speaking the polymer itself isn't changing, but the material overall will be more rigid than the polymer matrix due to the fiber support.
It is cement where a polymer such as SBR latex or PVA emulsion or other polymer is added to plasticize and make the cement more flexible.
No, plastics are far more flexible. Glass is pretty rigid
Sodium tetraborate is more commonly known as borax. It is often used as a cross-linking molecule between polymer chains, making the polymer more rigid.
Rigid means "stiff" or "devoid of flexibility". So being less frigid would mean being more flexible.
Rigid pipes are more likely to burst since they are more brittle and cannot travel as far when subject to strain.
Garbage bags are flexible due to them being made from specially structured hydrocarbons known as polyethene or (polythene) as we call it. In certain cases plasticisers can also be added to a material to make it more flexible. NOTE: Polyethene is a large polymer which is a long giant lattice of small individual monomers.
no it isn't flexible and that's a fact [Edited by 0siris] Some glass is made to be slightly flexible. In skyscrapers for instance, they make the window panes ever so slightly flexible so that when the pressure inside the building is equalized with the pressure outside the glass doesn't break.
No, Plants and bacteria have rigid cell walls. we humans have a membrane
In general, organic compounds that have rigid structures with multiple rings or bulky substituents tend to be the least flexible. Examples of such compounds include polycyclic aromatic hydrocarbons (PAHs) and sterols. These compounds have limited rotational freedom due to the constraints imposed by their rigid structures.
Fabric can be rigid depending on the type of material and weave. Fabrics like denim or canvas are examples of rigid fabrics, while fabrics like silk or satin are more lightweight and flexible. The rigidity of a fabric can also be influenced by any treatments or finishes applied to it.
Dancing will make you flexible because you are stretching your muscles.
More capable under severe service conitions and its more costly! Whoop whoop for NovaNet users! =]
