Elastomer or Rubber Material Guide

NBR is an excellent all around material for general industry. High overall value due to its top performance in many categories. Our proprietary blend which features the latest name brand ingredients have greatly increased the performance of this proven material.

CR, NEO, NE, N50 is an excellent hard wearing all around material for general industry with a nice rubber feel and memory.

Anverflex PUR is a new proprietary blend which is tough, and long wearing. It is non-marking and is long lasting as pressure and heat is used to cure - vulcanize the material in the molding process. Suitable for many applications where heat is not a factor. Shiny gloss finish.

SIT is excellent for high heat or food packaging. Soft and pliable, meets FDA Title 21 and German spec. BGVV (BGA) Part XV for contaminant-free load handling. Contains no dyes that can leach out when handling baked goods, drugs, glassware, hot products from molds, etc. Our new formulation minimizes almost completely the yellowing with age which use to occur with clear silicone in the past.

SI is excellent for high heat applications such as mold part removal or where heat resistance is required for large cups/seals. Silicone is also a good choice for cold outside applications as it stays fairly soft to lower temperatures than Nitrile or Neoprene.

S45 is excellent for EOAT high heat applications such as mold part removal from plastic injection machines requiring a soft touch. Higher durometer for bellows cups.

MD is a unique Silicone formulation made specifically for high heat applications in the baking food industry. This special rubber blend is designed for use with metal detection equipment used to safeguard food from metal objects as it is conveyed down the line.

NR is widely used and specialized for the printing, paper, and wood industries. It is low cost, non-marking, wears well and has a natural negative charge which allows it not gum up with ink or cut paper dust. While great for picking paper sheets up this is basically the same material used in rubber bands and is not suitable for general use. This material does not respond well to UV light, ozone, chemicals, oils, water etc.

Electro-Static Dissipative Nomastat™ ESD is a specialized proprietary rubber that can handle heat and is static dissipative for any industry where static buildup is a problem or explosion proof requirements exist. Applications are typically in the electronics, high tech, automation, packaging and printing industries. It actually bleeds any static build-up out through a ground of the machine or other ground designed into the system. Neutralized additives are blended in a special elastomer blend to diffuse static buildup. This elastomer blend has a insulating static-dissipating value of 97K  *CM  @  500 Volts.

TPU is an extremely tough material which darkens with UV exposure. It is sold under various proprietary trade names and the main market is hard caster wheels. We use TPU in static press applications such as bottle gripper bladders but rarely on cups anymore. We found it long wearing in static applications but usually too expensive to justify its use in vacuum cups which flex a great deal.  To compensate for the material's hardness, cups using this material must be designed with thinner walls which break down faster. While initially promising a few years ago, TPU's expense, hardness, lack of memory have proven to far outweigh its increased wear performance over other recently improved materials.

FPM is specialized for high heat jobs. It is best for static compression applications and has a stiff, somewhat dead feel for vacuum cups. It is also relatively expensive which limits its vacuum cup use. The newer High Heat Silicones have replaced Viton for most applications.

VYL is soft, low cost, and readily available in many grades for general light-duty or household use. Poured vinyl's or the clear vinyl used for push-on type suction cups are not suitable for industrial use. Vinyl will work for push on cups but they break down if repeatedly used for vacuum cups used in automation as they do not have good memory, tensile strength or mechanical properties.. Vinyl also handles heat poorly. The injection molded blended vinyl ANVER uses in its industrial vacuum cups is better, but you loose a key advantage of low cost to other materials.

NM is a new ANVER proprietary material which is non marking yet high wearing even in hot conditions. It is a silicone-free hybrid blend which is non marking and will not leave any residue, mold release agent or ghost-mark on products which need to be painted after handling. This material also handles high temperature and is extremely long wearing making it ideal for the plastic injection mold tooling (EOAT) industry. While not inexpensive this material is priced similar to other top quality urethanes but it offers higher overall value due to its excellent performance. In many applications where heat and non-marking are issues, Nomathane is the best blend available on the market.

GR is a new ANVER proprietary material which is long wearing yet extremely soft. It is a Rubber hybrid blend which is designed to be able to handle moderately rough materials such as sawn stone, textured plastic, fiberglass mat and saw cut wood surfaces. The rubber is so soft it can replace foam seals in many applications. It is the softest molded material available for large suction cups and is more economical than foam seals due to its durability.
