Neoprene

When talk about neoprene, very often we refer to a material used for the production of diving suits; of course this is true, but this is only one of the many possibilities! Today neoprene is not only used in sports field, in fact, they are increasingly requested by the most diverse markets, and the interest is much wider.
Neoprene is an artificial, spongy product with a microcellular structure; in some ways it is similar to rubber, but it is lighter and has a high thermal and insulation capacity, so this material acts as a barrier between different environments, such as between hot and cold, or between air and water.
Considering its spongy structure, neoprene is a protective material against, for example, insulation and impacts.

SHEICO neoprene is supplied in sheets , whose indicative size is 120 x 210 cm with a +/- 5% tolerance (caution : the measurements are not valid for certain types of sheets, for example with Kevlar or with rubber C. If you need to know the real size of a sheet, please contact us.

Sheet thickness, refers only to the foam (except lining), changes from a minimum of 0,5 mm to a maximum of 10 mm with +/- 0.3% tolerance. Concerning about cellular foams, all measures and dimensions are subjected to tolerance.

Neoprene can be used to produce different types of foams, which will modify the material technical features (density, thermal, elasticity, compressibility…), it can be pierced to allow perspiration and can be producted with low inflamable features blends.

With the term “neoprene” we intend only the rubber part of the material; the finishing parts can be defined as you like. Are available different choice whether rubber finishing (open cell, smooth, zigzaged….) or fabric typology which can be laminated above (nylon, polyester, lycra, felpa, elastic textile, more durable textile…. In a vast color selection). Sheets can be lined or not, sandwich, mono lined and double lined.

It’s also possible to purchase SBR sheets: a material that’s similar to neoprene. The difference is in the chemical composition that’s why is surely more economic beside the low quality. For some application this blend is more efficent.
Throght the most recent innovation, we find prestressed neoprene, more known as “crushed neoprene”.
Prestressed sheet is quite slim, particulary elastic and very resistant. The only limit is the weight, bigger than other materials.
In our warehouse we have available a large quantity of sheet prompt delivery; for not available sheet we can produce it according to specific requests, delivery time from 30 days to go.

FAQ (FREQUENTLY ASKED QUESIONS) ON NEOPRENE

Our neoprene is made in the Far East (Taiwan, Hong Kong, Japan …). Let’s see why …
First of all, it should be noted that the sheet of neoprene is commonly produced by breaking (CR) and by any laminated fabrics on one or both sides, or in special cases, even inside.
The main CR foams that we commercialize are “oil free”, ie they are entered without oil derivatives, a response of the will to live with the environment and with health.
The product sector in which the materials operate with certain characteristics of quality, comfort, resistance and softness, is what I have selected in the research and development of specific products for niche markets.
The neoprene made in Europe is mainly dedicated to the industrial market, and even if geographically more desirable, has some features that make it uninteresting in the “water sports”, clothing and accessories sectors.
The substantial difference is the quality of the fabric lamination: in the “water sports” sector, the tight bond of the fabric to the foam is fundamental, a cause of frequent use of the products in often aggressive environments (for example sea) .
For this reason the producers of sheets of paper are always more performing and more and more oriented towards respect.
The first “toluene free” glues are currently being tested, making a decisive step towards increasingly ‘green’ products.

Neoprene is sold in sheets, whose indicative dimension is of cm 120×220 (+ /-5%)
Yes, neoprene is an impermeable material; under normal conditions, its closed microcells structure , doesn't allow the passage of air / water.
  • - wash at 30 °C with a common detergent
  • - Do not bleach
  • – non stirare nè utilizzare altre fonti di calore
Currently the sheets have a minimum thickness of 0.5 mm.
Neoprene sheet is usually proposed in tre versions:
  • Double-lined: both faces are covered with fabric
  • Single-lined a single face covered with fabric
  • Not lined: no face covered with fabric
The most frequently laminated fabrics are in nylon or polyester yarn. They can have different weights depending on the required functionality.

Nylon is the widely used fabric, other than fluorescent colors and very light colors, in which a very opaque polyester is used, to keep the colors very bright, without showing the color of the neoprene to which it is laminated.

During the lamination of the neoprene, fabrics are applied with solvent-based or water-based adhesives.
It is a very remote event but not impossible: if the neoprene is used in marine environments, the salt as well as the UV rays, can deteriorate the material, but using the best glues, developed for this type of use, reduces drastically the possibility of delamination.
All dark colors are on average very resistant; there is a more rapid deterioration / discoloration in light colors and especially in fluorescent colors, due to a less UV-resistant pigmentation.
the sides of neoprene sheets, when they are not lined with fabric, can have different finishes:
  • - Smooth (smooth skin Glide): surface is uniformely smooth. It can be natural black or coloured
  • - Open cell: suface can be porous
The elasticity of the sheet depends on the elasticity of the laminated fabrics. The sheet will have the elasticity equal to the less elastic laminated fabric.
Yes, especially the non-laminated sheet, which is not lined with fabrics.
Yes, the neoprene panels can be joined together with gluing, in order to maintain and guarantee the impermeability of the product and can be sewn. If you do not want to affect the impermeability of the product, the seam must be non-passing.
The seam can be applied only if linings are on both panels.
To combine the neoprene, it is recommended to use neoprene-based glue. This glue will not be optimal if you try to glue something on the neoprene lining.
When it is necessary to sew a sheet of non-lined neoprene by machine, there is the problem of how to prevent the rubber from jamming in the machine's mechanisms.
In fact, the rubber makes friction on the roll, the sheet does not flow, the thread is tied ... and the seam is difficult, if not impossible.

To overcome this problem we can:
  • - use a sewing machine with a double transport foot
  • - Place a sheet of tissue paper between the rubber and the roller of the machine
  • - Use special silicone sprays that make the rubber and the needle slippery.
DIFFERENT TYPES OF SEAMS
OVERLOCK
Overlock seam, in our sector, is generally used for two types of applications:
  • - finishing of hems
  • - fast assembly of very low thickness panels
Finishing: in addition to a nicer appearance, Overlock seam finishing edge / rim (of a sleeve, a pant, hood ..) protects the product from small delamination and fraying.
Assembly: many neoprene accessories are packaged with this seam, which does not require the pre-pasting of the parties. Overlock seam does not guarantee any resistance.

FLATLOCK
It ‘s a flat seam, very resistant also suitable for thin neoprene. It ‘s very decorative but isn’t waterproof; It can be made simultaneously using different colored yarns.

BLINDSTITCH
Is the typical stitching for neoprene products: the needle does not completely perforate the neoprene, so the seam is waterproof and the chain structure ensures elasticity.

WELDED There are no seams but neoprene is only glued
