HEALTH & SAFETY
Toxicity caused by NTSTRENGTH WS-125 products alone and when incorporated into papers and paperboards, has not been reported so far. The content of NTSTRENGTH WS-125 is listed under Title 21 of the Code of Federal Regulations, Paragraph 176.170. However, contact with the NTSTRENGTH WS-125 solution should be avoided because of its acidic nature. When exposed to the solutions, wash with fresh water immediately.
WHAT is PAE – WET STRENGTH AGENT ?
The need for a wet-strength resin which could be used in neutral or alkaline papermaking led, over fifty years ago, to the development of poly(aminoamide)- epichlorohydrin (PAE) resins, sometimes referred to as polyamide-polyamine- epichlorohydrin (PPE) resins.
A dibasic acid is condensed with poly-functional amine to give a water-soluble polyamide. The secondary amine groups of the polyamide are then alkylated with epichlorohydrin, and a number of reactions take place. The resulting product consists of relatively low molecular weight polyamide backbones with many reactive side chains. Chloride counter-ions are formed as a result of the epoxidation and, at the end of the manufacturing process, the resin is usually acidified to provide stability against gelation during storage.
As the resin is dried in a paper sheet, the hydroxyazetidinium groups have two possibilities for reaction. One is to react through the amine groups of other resin molecules to give a homo-crosslinked network, and the other is to react with available carboxyl groups in the paper.
The wet strength is not fully developed by the time a paper product reaches the end of a paper machine, and strength continues to develop as the paper is stored. The rate of curing is affected by the temperature and the length of time in contact with heat. The bonds that are eventually formed are not readily broken under either acid or slightly alkaline conditions, and the wet strength is therefore permanent. Whilst this can be an advantage in certain applications, it does make the paper or paperboard more difficult to disintegrate. However, the difficulties for the disintegration of PAE-treated paper have not been reported practically when the dosage level of PAE resin is below 4%.
PAE resins are most often used in a pH range of 6 to 8, but their efficiency is adequate in the pH range 5 to 9. Reducing the pH of a papermaking furnish leads to two effects that discourage adsorption. Firstly, fewer carboxyl groups on the pulp are dissociated. Secondly, although most of the charge on the PAE resin is due to the azetidinium groups, which are insensitive to pH change, there are some tertiary amine groups present in the polymer and these lose their charge at lower pH.
PAE resins are used extensively in all types of wet-strength papers. Major examples are household products such as paper towels, napkins, facial tissue, and packaging materials like liquid packaging, corrugated boxes, paper bags, and specialties such as photographic papers, wrappings and disposables.

NTSOFT 8015
Releasing Agent
NTSOFT 8015 have been designed specifically to be added to paper stock by wet end addition for the purpose of softening tissue and absorbent papers or by the surface spray application method to improve Yankee drier crepe release properties. NTSOFT 8015 contains a blend of fully refined mineral oil, which has a slight petroleum odor, esters and nonionic surfactants that makes this product easily emulsify in water. In most cases this slight odor is not objectionable. NTSOFT 8015 is specifically formulated as an effective crepe release in the MFG of tissue and towel products. It is compatible with all commercial crepe adhesives, to provide the proper balance for effective creping.
1. Typical Properties
A.Specific Gravity : 0.860 +- 0.015
B.Appearance : Light Yellow Clear Liquid
C.Viscosity : > 100 cps
D.Solubility : Easy to mix with WATER
E.Stability : Stable above 5C
2. Application
NTSOFT 8015 agent forms spontaneous emulsion upon dilution with water. The preferred method of dilution is addition of the product to water, rather than the reverse. The concentration can be varied at will, but normally a 10% emulsion is most suitable.
NTSOFT 8015 is applied trough the spray boom onto the Yankee dryer surface.
For maximum effectiveness of the product, the system should be maintained at pH 7.0 or below.
NTSOFT 8015 should not be used in a system containing rosin size. The oils apparently combine with the rosin size to soften it, and a very sticky combination result.
The required amounts of NTSOFT 8015 will vary. For internal application, 3 to 7% based on fiber weight, have been found most beneficial. For surface application emulsions of 0.5 to 3.0% concentration have been found extremely beneficial for controlling Yankee drier release properties.
3. Storage
Under some storage conditions, a separation of the emulsifier may occur. Storage above 5C will normally prevent this.
Should separation occur, moderate stirring or mixing, with no resultant loss of efficiency can return the product to their normal state. Generally, rolling of the drums around the floor will be sufficient to assure remixing of the component
4. Packing and Delivery : 180Kg Drum / Export Standard Packing.

NTSOFTER IMS-100
Softening Agent for Tissue
NTSOFTER IMS-100 is a synergistic combination of materials that is effective as a softening agent for tissue. It is also an excellent debonding agent for use in the production of fluff pulp. IMS-100 is a water-dispersible, concentrated product with low foaming potential. This product can be dispensed directly from the shipping container by a chemical-metering pump or suitable measuring containers. It disperses easily in water and aqueous systems.
A. Typical Properties
i. Specific Gravity : 1.020 +- 0.010
ii. pH : 5 - 7
B. Application
i. We recommended Input place must be suction part of Fan pump, White water into Fan pump, or paper stock before fan pump. But it is depend on manufacturing condition and, it must input in some place that enough mixing is achieved.
ii. Input dosage is different between using for softener and Debonder.
For Softener is around 1kg per 1ton of paper, and for Debonder is around 3kg per 1ton of paper.
C. Advantage
i. Increased Paper Surface softness
ii. Improved sheet flexibility
iii. Improved Feeling and Touch
iv. Increased bulk softness
D. Storage
i. Under some storage conditions, a separation of the emulsifier may occur. Storage above 5C will normally prevent this.
E. Packing and Delivery : 200Kg Drum / Export Standard Packing.
