Product Description

ECOPULP®E5000 is an esterase produced by a strain of Trichoderma reesei (Trichodermareesei) that has been genetically modified. Its main activity is the hydrolysis of carboxylic acid esters, including the hydrolysis of long-chain carboxylic acid esters. ECOPULP®E5000 is a multifunctional esterase classified as a carboxylic ester hydrolase. This product can be effectively used for the finishing of cellulose raw materials, especially for the treatment of paper and wood pulp.

Product Properties

Product Application

ECOPULP®E5000 is a highly concentrated liquid esterase. It was developed specifically for the processing of paper and wood pulp hydrolysates. The enzyme can be used in conjunction with other papermaking aids to expand its functionality.

ECOPULP®E5000 treatment has the following benefits to the papermaker:

1. Reduce the amount of extract in chemical pulp

2. Reduce the stickies of recycled pulp

Recommended product application conditions:

Enzyme dosage: 20-500g/ton pulp raw material

Pulp PH:4.5-7.5

Temperature: 20-75 ℃

Processing time: 15-60 minutes

Storage conditions and shelf life

The enzyme gradually loses activity over time, depending on the storage temperature. Recommended storage conditions are 1-10°C, in sealed containers, away from direct sunlight. When stored at room temperature (20-25°C), the activity of the product does not drop below 95% of the nominal enzyme activity for months from the date of shipment.

Storage at 1-10°C reduces the loss of enzyme activity. Prolonged storage and/or adverse conditions involving higher temperatures may result in a rapid loss of enzyme activity, requiring increased enzyme dosage.

The product should be protected from freezing

Safe disposal
Use should avoid unnecessary direct contact, and avoid the formation of dust and spray. Repeated inhalation of enzyme dusts and sprays may cause allergies and may cause sensitization reactions in sensitive individuals.
