    Confused Rubber? Silicone? PVC?...straps?

    Hi,

    Some of us collect watches and keep all of them, some of us just buy and later sell and like me probably had over hundreds of watches since your watch ''addiction'' started.

    Some of you also buy alot of watch strap and bands to satisfy your taste.

    I've learned many things in the years about watches, the different parts, material used for watches, crystal material this vs that, etc... but one thing that is still not clear to me is all the different kinds of materials used for making watch straps.

    I've had straps made of: Rubber, Silicone, Urethane, Polyurethane, etc...We know also that sometimes more expensive does not mean more quality.
    For exemple the most durable one I've owned is the Citizen strap with the depth rating printed on which can be purchased for $25. ( which I don't know the material it's made of)

    What is the difference between all these materials?
    Which is the most resistant in the long run?
    Which has less tendency to tear?
    Which is the best for a watch that will be used for diving?

    Time is an artificial unit created to give us the illusion of control.
    Time is the product of our focus on a linear existence, but our true existence is circular.'.

    Ive only had rubber and silicone, which I got from watchadoo. Its the most flexible and comfortable band I have. That said, the Maratec and Maratec Elites are supposed to be comfortable also. You may want to consider checking those out too

    I had the same Citizen strap, and your right, they were great.
    My experience with Silicone, is it perishes more quickly than other types.
    But i think your a touch wrong about expensive is not always better. While that is semi true, i have found, no matter the product, down to the shoes on your feet, " you get what you pay for "

    I think I'm right since I did say ''We know also that sometimes more expensive does not mean more quality''

    Yes Mate, thats why i put " Semi true "

    You dont always get what you pay for, but i try to buy things once, and have even converted my Wife, who has very tight purse strings, to the same way of thinking.

    I totally agree with trying to buy things once. Talking about the wife, I'm trying to convince mine that the Volvo CX90 would be a good thing for us. We'll see how she buys that!

    Any rubber, plastic material specialist here on the forum that could put some light on this thread?

    Re: Rubber? Silicone? PVC?...straps?

    Rubber -
    1. A yellowish, amorphous, elastic material obtained from the milky sap or latex of various tropical plants, especially the rubber tree, and vulcanized, pigmented, finished, and modified into products such as electric insulation, elastic bands and belts, tires, and containers. Also called caoutchouc, India rubber.
    2. Any of numerous synthetic elastic materials of varying chemical composition with properties similar to those of natural rubber.

    Silicone (rubber) -
    1. A rubber-like material composed of silicone—itself a polymer containing silicon together with carbon, hydrogen, and oxygen. During manufacture heat is required to vulcanize (set or cure) the silicone into its rubber-like form. This is normally carried out in a two stage process at the point of manufacture into the desired shape, and then in a prolonged post-cure process.

    PVC (polyvinyl chloride) -
    1. A thermoplastic polymer. It is a vinyl polymer consisting of vinyl groups (ethenyls) that are bound to chlorine. Polyvinyl chloride is the third most widely produced plastic.

    Polyurethane (aka urethane) -
    1. Any polymer consisting of a chain of organic units joined by urethane (carbamate) links. Polyurethane polymers are formed through step-growth polymerization by reacting a monomer containing at least two isocyanate functional groups with another monomer containing at least two hydroxyl (alcohol) groups in the presence of a catalyst.

    Which is "best"? Since, all of these compounds are general categories of material, the specific properties are defined by the specific formula used in each, i.e., there are many different compounds used in rubber, silicone, polyurethane and PVC, each have slightly different properties that have to (or, can be) tailored to fit the specific application.

    Re: Rubber? Silicone? PVC?...straps?

    The best is rubber. I have had some of my rubber straps for years and they still look great. Silicone is junk and should not be used for straps. I have had a few that I had tear on me in a short period of time. Beyond that they are lint collectors. PVC lasts a long time but is plastic and does not belong on a high end watch. Urethane is my second choice behind rubber but it will break down after a few years. I have noticed that a few makers have been advertising straps as polyurethane but they have been silicone.

    Regards,

    Ren

    Well other than the fact that you think that plastic does not belong on a high end watch, would PVC be more resistant therefore last longer than rubber? To me if a strap looks good and is resistant I would not mind that it's PVC. I'm a diver and alot of my gear is made of plastic probably PVC and I can say that it is top notch gear. My watch is part of my equipment also...so a bit of PVC won't bother me! So in that case what would be the difference between Rubber and PVC on a material proprety aspect?
