Mediaplast NB 4 is a special adipine acid plasticizer at an exceptionally reasonable price for the use in polar polymers like NBR, H- and XNBR, CM / CSM, CR, ECO, etc.
Mediaplast NB 4 is, due to its relatively low volatility and also because of its extremely low setting point, suitable for heat-resistant as well as cold flexible rubber articles (see technical data).

The production of rubber products with a cold flexibility lower than - 40 °C is possible, for example.
Compared to mineral oil plasticizers as well as many ester plasticizers the compatibility within NBR compounds is much higher.
In the contrary to more volatile and often more expensive ester plasticizers, Mediaplast NB 4 does not cause soiling on the molds.

If polymethacrylates come in contact with Mediaplast NB 4 containing compounds, they are not influenced negatively (test at 70 °C, 21 days).
Mediaplast NB 4 is a special adipine acid plasticizer.
Due to its relatively low volatility and extremely low setting point, Mediaplast NB 4 is suitable for heat-resistant as well as cold flexible rubber articles.

Due to the characteristic light color of Mediaplast NB 4, it can also be used for the production of light or colored rubber compounds.
As the softening effect of Mediaplast NB 4 is especially high, the dosage should be reduced slightly, when comparing tests are run.
This should also be considered when judging swellings in different media.

Mediaplast NB 4 is an industrial plasticizer — more specifically, a specialty ester plasticizer based on adipic acid esters, designed for use in polar polymers and elastomer/rubber compounds. 

Mediaplast NB 4 is typically supplied as a clear, colorless to pale-yellow liquid with a mild ester‑like odor. 
Because Mediaplast NB 4 is a formulated plasticizer blend (rather than a single defined low‑molecular‑weight chemical), it does not have a public CAS number or EC number listed.

USES and APPLICATIONS of MEDIAPLAST NB 4:
Due to the characteristic light color of Mediaplast NB 4, it can also be used for the production of light or colored rubber compounds.
As the softening effect of Mediaplast NB 4 is especially high, the dosage should be reduced slightly, when comparing tests are run.
This should also be considered when judging swellings in different media.

Mediaplast NB 4 is a special ester plasticizer for use in polar synthetic rubbers such as NBR, NBR/PVC, HNBR, CR, ACM, ECO, and similar materials.
Mediaplast NB 4 exhibits very low volatility at elevated temperatures, yet has a low pour point, making it ideal for the production of heat-resistant vulcanizates that remain flexible even at lower temperatures.

Primary use of Mediaplast NB 4: plasticizer/tackifier for polar rubbers — NBR, NBR/PVC, HNBR, CR (chloroprene), ACM, ECO and similar elastomers.
End products: Mediaplast NB 4 is used seals, hoses, gaskets, fuel-resistant parts, cold-flexible rubbers, and other technical rubber articles where both heat resistance and low-temperature flexibility are required.

Mediaplast NB 4 has low volatility and very low pour point give good heat resistance and excellent low-temperature flexibility (suitable for parts that must perform below −40 °C).
High compatibility with polar polymers like NBR — Mediaplast NB 4 leads to good plasticizing effect without mold soiling.

Non-staining and light color — Mediaplast NB 4 is suitable for light/colored compounds.
Mediaplast NB 4 is cost-effective adipate plasticizer alternative for polar elastomers (noted as “exceptionally reasonable price” in the leaflet).

Because Mediaplast NB 4 is highly effective (strong softening effect), adjust phr vs. other plasticizers when replacing or comparing to avoid overdosing.
If color or staining is critical, confirm lot color and run small trials — leaflet notes suitability for light-colored compounds but recommends compatibility testing.

Mediaplast NB 4 is used widely as a plasticizer and softener in polymer and elastomer formulations. 
Mediaplast NB 4 is used in NBR, HNBR, CR (chloroprene rubber), CM/CSM, ECO, and other polar synthetic rubbers. 

Mediaplast NB 4 is used production of rubber articles needing heat resistance and cold flexibility (e.g. rubber parts that must remain flexible at low temperatures, even as low as –40 °C). 
Mediaplast NB 4 is used in PVC formulations — flexible PVC, PVC hoses and tubing, PVC cables (for cable insulation) — to provide flexibility and softness. 

Mediaplast NB 4 is used for automotive rubber components (e.g. oil seals, hoses, gaskets) owing to its stability with oils, water, and detergents. 
Mediaplast NB 4 is used for flexible tubing, hoses, and industrial rubber‑plastic blends — where good filler dispersion, processability, and long-term mechanical properties are needed. 

Mediaplast NB 4 is used for potential use in synthetic leather (coated fabrics), flooring, wall coverings, sealants, adhesives, plastisols, and other PVC‑ or elastomer‑based products where softness, elasticity, and durability are required. 
Because of its light color, Mediaplast NB 4 is suitable when the final product is light-colored or colored (rather than dark rubber mixtures), which is sometimes a limitation with darker plasticizers. 

-Plasticizer uses of Mediaplast NB 4:
Compatible Polymers & Resins: Chloroprene Rubber (CR), Nitrile Butadiene Rubber (NBR)
End Uses of Mediaplast NB 4: Footwear, Housewares, Sporting Goods, Tires, Tubing

BENEFITS of MEDIAPLAST NB 4:
Using Mediaplast NB 4 brings several advantages over other plasticizers (especially mineral oil-based plasticizers or more volatile esters):
High efficiency — Mediaplast NB 4 achieves good softening/flexibilizing effect even at moderate dosage. 
Mediaplast NB 4 is improved cold‑temperature performance — extremely low setting point ensures flexibility at very low temperatures (e.g. –40 °C). 

Low volatility and low migration — Mediaplast NB 4 reduces volatile losses during processing, and helps maintain long-term flexibility in finished products without plasticizer loss. 
Good thermal stability — Mediaplast NB 4 is suitable for heat-resistant applications. 

Compatibility with polar elastomers and PVC — Mediaplast NB 4 offers better compatibility with polar rubbers (like NBR) than many mineral-oil or non‑polar plasticizers. 
Light color, low odor — Mediaplast NB 4 is useful when final product appearance requires lightness or color. 

Resistance to extraction by oils, water, or detergents — Mediaplast NB 4 is beneficial for products exposed to such conditions (e.g. automotive seals, hoses, cable jackets). 

SUMMARY / KEY NOTES & LIMITATIONS of MEDIAPLAST NB 4:
Mediaplast NB 4 is not a simple standard chemical with a fixed CAS/EC — it's a formulated plasticizer blend (ester‑based), so CAS/EC number is listed as “not applicable.” 

Because of Mediaplast NB 4's high softening effect, when used instead of other plasticizers you may need to reduce dosage slightly to achieve comparable hardness/flexibility — otherwise over-softening may occur. 

It is especially well-suited for polar polymers / elastomers (e.g. NBR, CR, HNBR) — Mediaplast NB 4 is used for non-polar rubbers or polymers, other plasticizers (from the same product line) may be more appropriate. 

Because it's a formulated product, detailed chemical composition (exact ester molecules, molecular weight) is proprietary and typically not public — i.e. you will not find a simple molecular formula or single CAS for “Mediaplast NB 4.
