Natural Latex
Natural Latex is produced from the Hevea Brasiliensis rubber tree. These trees are grown on large plantations, primarily found in Thailand, Indonesia, Malaysia, and Liberia.
Natural Latex is a cloudy, white liquid that is collected by cutting thin strips of bark from the tree, and allowing the latex to drop into collecting vessels. The latex is then gathered, poured into containers, and delivered to a processing station where it is strained & concentrated.
The latex is placed into a centrifuge, stabilizers are added, and the latex is centrifuged to remove some of the water & increase the rubber content of the latex. After centrifuging, the material is known as latex concentrate, and contains roughly 60% rubber.
This latex concentrate is then compounded by Chemionics Corporation by adding other raw material ingredients. These raw materials are water-based dispersions which are added to the latex to achieve the desired performance characteristics.
Chemionics produces high quality, custom formulated natural latex compounds for a multitude of market applications & processing possibilities.
Chemionics offers formulations using both high & low ammonia natural latex, as well as offering pre-vulcanized compounds.
To assist our customers with their manufacturing & processing of our latex compounds, Chemionics also produces specialty additives, dispersions, and coagulants.
Our technical laboratory is available to develop the formulation you require, as well as assist in the application & processing of our compounds to meet your exact needs.
See our Water-Based Compounding Capabilities Brochure.
Some of the primary natural latex product categories are as follows:
Dipping Compounds
Chemionics produces natural latex compounds that are tailored to meet the stringent requirements of straight dipping & coagulant dipping processes used in the manufacture of medical products such as surgeon & exam gloves, catheters, and re-breather bags. Some product applications for latex dipping compounds include:
- Surgeon / Exam Gloves (unsupported)
- Household Gloves (unsupported)
- Catheters
- Toy Balloons
- Breathing Bags
- Industrial Work Gloves (supported)
- Finger Cots
- Isostatic Bags
- Bellows / Bulbs / Boots
- Latex Tubing
- Squeeze Toys
- Automotive Parts
Cohesives (Cold-Seal / Self-Seal Adhesives)
Chemionics manufactures a complete line of high performance, water-based cohesives used in many packaging & paper converting applications. Surfaces coated with cohesives will only adhere to other surfaces coated with the same cohesive.
These adhesives offer low VOC’s, and can be custom formulated as follows for:
- FDA Compliance for indirect food contact
- Viscosity
- Total Solids
- Custom Colors
- Tack / Bond Levels
- Coating & Application Methods
These natural latex cohesives can be formulated specifically to be coated onto paper, foam, foil, and various films & fabrics. Product applications include:
- Self-Seal Envelopes
- Napkin Wraps
- Currency Wraps
- Protective Wrapping Materials
- Bandage Wraps
- Candy Wrappers
- Medical Packaging
- Luggage Tags
- Apparel Wraps
Casting / Slush Casting Compounds
These compounds are pre-vulcanized natural latex used to produce hollow, flexible products by slush casting into plaster molds. The latex sets-up as a result of water in the latex being absorbed into the plaster mold, depositing a wall of gelled latex on the mold surface. The excess latex is then poured out of the mold, the remaining layer is partially dried, and then removed from the mold and completely dried. Product applications include:
- Halloween Masks
- Flexible toys
- Halloween props & special effects
- Doll Bodies
Mold Making Compounds
These compounds have been developed for making flexible, durable rubber molds. These compounds can be brush applied, sprayed, or dipped to create the desired rubber mold.
Our high quality formulations yield excellent surface reproductions & the finest detail. The major uses are for making molds when pouring concrete & plaster for the following applications:
- Architectural Restoration
- Manufactured Stone Veneer
- Ornamental Concrete / Statuary
- Wax Candle Making
- Plaster Statuary
Some of our more popular mold making compounds are:
- 61-1000 Series
– Brush/Spray Applied
– 74-76% Total Solids
- 60-1600 Series
– Brush/Spray Applied
– 55-62% Total Solids
- 60-1300 Series
– Dipping Compound
– 56-60% Total Solids
Custom Formulations Also Available!
GenGrip Foam Adhesive
A one-part, water-based, natural latex adhesive specifically developed for adhesion for foam to foam applications. This adhesive is predominately used in the upholstered furniture and foam mattress industries. The adhesive can be sprayed or brush applied to the foam. This adhesive bonds rapidly & reliably, as is required for these applications. Being water-based offers a solvent-free alternative to the existing solvent-based adhesives historically used for these applications. The advantages of GenGrip include:
- Develops a high level of tack instantly
- Superior bond strength
- Passes Cal 117 Flammability Spec
- Non-hazardous / environmentally friendly compound
- Contains no VOC’s
- Easy clean-up of equipment with soapy water
- Exceptional “mileage”
- Custom colors also available
