The BEPL product range is manufactured under strict quality processes and procedures. BEPL is an ISO 9001:2000 company, a symbol of our dedication to our customer value enhancement. BEPL has a strong Research and Development program to improve internal processes, develop applications and aid our clients in adding value to their products. BEPL’s extensive Research and Development efforts help in developing ABS grades for client specific applications.
Tailor making just one for you has been a success mantra for BEPL. Our Technical Services Personnel are the best in the business, using their skills to resolve problems and improve client processes.
After assimilation of technology, the focus shifted towards development of better grades with out increasing the cost of product, Improvement of manufacturing practices in Polymerization and Compounding to enhance the quality of product and to increase the level of consistency in quality. This has now become a continuous ongoing culture in this company.
Business activities here at Bhansali are well integrated with centralized Research and Development cell located at Chhindwara plant. Research & Development has been playing a significant role to absorb new technology practices and develop new ABS grades.
There are three keys to the success of our Research and Development activities:
- Keeping our eyes and ear open for current and future customer needs,
- Acting as a sensitive radar for the latest scientific trends and
- Dedicated employees.
We therefore ensure that our research and business units work in close co-operation with external partners in particular from the customer industries. The three stages development phases are
Phase I: 1990-1995 :
In this period BEPL was mainly focused attention on assimilating and absorbing the technology of ABS polymer and compound manufacturing obtained from Sumitomo, Japan.This technology was fully based on Emulsion Polymerization techniques and Latex Master Batching concept for making an individual ABS pellet grades. Barring sheeting grades and other high impact extrusion grades, development activities were mainly oriented to fine-tune most of the injection molding grades like IM-17 A, IM-11 etc.
Phase II: 1995 to 1998:
Concept of High Rubber Graft + SAN compounding for all the Injection molding grades was developed and implemented. HRG with higher rubber contents was developed.Moreover some Latex Master Batch formulations were also developed and implemented for Export sheet extrusion , very high impact grade , Antistatic Grade etc. Another most significant development was introduction of non-sintering route to produce very high heat resistant gradesbased on AM-SAN having heat distortion temperature of 112 deg c + with excellent processibility.
From 1999-2002:
During this period, BEPL stabilized the process of HRG manufacturing and formulated and developed two different HRG systems, one was bimodal HRG (HRG-50I) with 50.73% of rubber and another was unimodal HRG (HRG-SH) with 48% rubber. All injection molding grades be it general purpose, be it very high impact, were formulated thru HRG-50 I. All extrusion grades were being made from HRG-SH (M) with some medium Impact medium flow injection molding grades as well. Up on taking over of Polychem in 1999, Bulk SAN was also introduced into formulations which immensely contributed to reducing the cost of compounding formulations, improving ABS processability and physical property balance. Property comparison of some of the new grades developed against the grades of well established global players is given in Annexure A and B hereto.
Phase-III : New Processes and New Products:
New processes and new products these are two elements in our innovation strategy that have made Bhansali to create edge on the material produced by the competition. This phase was basically more focused on the development on the Polymerization side. We developed a concept of One-Polybutadiene- Two-Graft- Two-Powder system with two SAN grades so as to make use of our resources at optimum level.
New processes and new products to create an edge over material produced by competition have been developed which has been implemented from January,05. In this respect concept of SPS PBDE followed by Agglomeration Process and two graft Powder with two Bulk SAN have been developed and implemented, this has given further benefits in terms of lower cost and higher product quality.
A: SAN Co-polymer by Mass Continuous Polymerization:
-
-
Final SAN Co-polymer from catalysis process, which has been adopted, gives superior color.
-
Operational ease, process of polymerization control is very smooth, because Polymerization can be carried out at lower temperatures,
- 60 % increase in the productivity at same temperature of Polymerization has become feasible
- Since the out put has increased, Operational cost has been reduced and
Quality up-gradation of finished product becomes possible due to the benefits enunciated at point 1 and 2 above.
B: Agglomeration Technology for PB Latex:
BEPL has developed a process of Agglomeration of Polybutadiene which has reduced the reaction time from average of 46 Hrs to 23 Hrs, hence productivity of polybutadiene manufacturing has increased by 50 %. In addition to this properties of final product have also got enhanced substantially with the same product formulation.Principle of agglomeration is basically to generate very small and discrete rubber particles in the Polybutadiene polymer by speeding up the reaction and then agglomerating it both chemically and mechanically in to the desired size of rubber particle. This agglomerated rubber particles are subsequently grafted in situ by Styrene and Acrylonitrile to get a Graft High Rubber Graft Co-polymer
 Property Modifiers: Heat Property Modifiers for commodity plastics and Impact Modifiers for r-PVC, Transparent PVC, Nylons etc have been developed and commercialized
Heat Modifier:
AMSAN –S 1250B is a lightfast and weather resistant property modifier for improving the heat resistance (Vicat Softening Point) of rigid PVC. In addition to this, AMSAN-S1250B is suitable for improving the ease of calendaring and thermo formability of rigid PVC and it also enhances the dimensional properties of u-PVC by increasing the value of Tensile Strength and flex modulus. This is basically a heat property modifier, heat properties like heat distortion temperature and vicat softening point of low end polymers can be modified by using this polymer heat modifier resin. This is based on Alpha-methyl Styrene and Acrylonitrile and universally used to enhance service temperature and continuous use temperature of plastics such as PVC, ABS and Polyamides.
This product is in resin form having fine particle distribution for facilitating the blending and alloying of this polymer with the polymers being modified for Heat Properties,
Features of this product are
- Free flowing white powder,
- Efficient heat distortion temperature and Vicat Softening Temperature modifier for PVC, ABS, PVC, Polyamide, ASA etc.
- Excellent Compatibility with r- PVC resins and compounds,
- This is a Co-polymer with lower specific gravity which after getting alloyed with Polymers like PVC reduces the specific gravity of the final blend.
Impact Modifier: Opaque & Transparent Applications :
“ABSTRON-BL 60” is a modifier for improving the Impact Strength of Polyvinyl Chloride In addition, “Abstron-BL 60” is suitable for improving the ease of processibility and thermal stability PVC. In addition to this, BL-60 is suitable for improving the ease of calendaring and thermo formability of rigid PVC and it also enhances the dimensional properties of u-PVC.
Features of this product are,
