What is NR Latex?

Answer 1

Latex Rubber is a complex fluid made up of different chemicals and displaying varying characteristics depending on its type. In basic terms, we can define it as a milky fluid exuded from the rubber plant.

There are 2 different types of latex rubber: Latex natural rubber (NR) and Latex synthetic rubber (SBR). Synthetic rubber comprises: Polyisoprene (IR); Polybutadiene (also known as Buna rubber (BR)); Styrene – Butadiene copolymer (Buna-S rubber (SBR)); Ethylene – Propylene copolymer (EPDM); Polyisobutylene (Butyl rubber); Polychloroprene (Neoprene rubber (CR)); Acrylonitrile – Butadiene copolymer (Nitrile rubber); Polyacrylate; Polyurethane (PU); Polysilicone (Silicone). Each type of rubber has its own characteristics due to the differences in chemical structure. There are many kinds of latex synthetic rubber and currently manufacturers use latex synthetic rubber (SBR) to make mattresses.

Latex natural rubber (NR): Also called Latex Polyisoprene Natural Rubber is exuded from the rubber plant, mainly from Hevea Brasiliensis (Euphorbiaceae family) by tapping.

There are three different stages in the structuring of Latex NR:

Dispersing stage: Polyisoprene rubber particles are synthesized with the help of enzymes. Polyisoprene has a high structure of harmonisation. Its characteristics range from the same cis-isomer, high volume of homogenous molecules and high bonding level.

Serum stage: Latex becomes serum which consists of diverse contents including water (52% – 70%), protein (2% – 3%), fatty acid and derivatives (1% – 2%), glucid and heterosid (around 1%), minerals (0.3% – 0.7%).

Stabilising stage: Latex consists of protein. During preservation, NH3 should be added to avoid coagulation and disruption of it’s metabolic structure due to micro-organism activities

Answer 2

my guess would be non rubber, or something along those lines. A lot of people are allergic to the resins in rubber, which is what latex is made from.
